We should not unref the model here, it might not even exist anymore.
Instead check if it exists and only use it if it does.
The unref was leftover from a previous fix in
ba9f53397f.

/*** Structure: how GtkFileSystemModel works
|
||
*
|
||
* This is a custom GtkTreeModel used to hold a collection of files for GtkFileChooser. There are two use cases:
|
||
*
|
||
* 1. The model populates itself from a folder, using the GIO file enumerator API. This happens if you use
|
||
* _gtk_file_system_model_new_for_directory(). This is the normal usage for showing the contents of a folder.
|
||
*
|
||
* 2. The caller populates the model by hand, with files not necessarily in the same folder. This happens
|
||
* if you use _gtk_file_system_model_new() and then _gtk_file_system_model_add_and_query_file(). This is
|
||
* the special kind of usage for "search" and "recent-files", where the file chooser gives the model the
|
||
* files to be displayed.
|
||
*
|
||
* Each file is kept in a FileModelNode structure. Each FileModelNode holds a GFile* and other data. All the
|
||
* node structures have the same size, determined at runtime, depending on the number of columns that were passed
|
||
* to _gtk_file_system_model_new() or _gtk_file_system_model_new_for_directory() (that is, the size of a node is
|
||
* not sizeof (FileModelNode), but rather model->node_size). The last field in the FileModelNode structure,
|
||
* node->values[], is an array of GValue, used to hold the data for those columns.
|
||
*
|
||
* The model stores an array of FileModelNode structures in model->files. This is a GArray where each element is
|
||
* model->node_size bytes in size (the model computes that node size when initializing itself). There are
|
||
* convenience macros, get_node() and node_index(), to access that array based on an array index or a pointer to
|
||
* a node inside the array.
|
||
*
|
||
* The model accesses files through two of its fields:
|
||
*
|
||
* model->files - GArray of FileModelNode structures.
|
||
*
|
||
* model->file_lookup - hash table that maps a GFile* to an index inside the model->files array.
|
||
*
|
||
* The model->file_lookup hash table is populated lazily. It is both accessed and populated with the
|
||
* node_get_for_file() function. The invariant is that the files in model->files[n] for n < g_hash_table_size
|
||
* (model->file_lookup) are already added to the hash table. The hash table will get cleared when we re-sort the
|
||
* files, as the array will be in a different order and the indexes need to be rebuilt.
|
||
*
|
||
* Each FileModelNode has a node->visible field, which indicates whether the node is visible in the GtkTreeView.
|
||
* A node may be invisible if, for example, it corresponds to a hidden file and the file chooser is not showing
|
||
* hidden files.
|
||
*
|
||
* Since not all nodes in the model->files array may be visible, we need a way to map visible row indexes from
|
||
* the treeview to array indexes in our array of files. And thus we introduce a bit of terminology:
|
||
*
|
||
* index - An index in the model->files array. All variables/fields that represent indexes are either called
|
||
* "index" or "i_*", or simply "i" for things like loop counters.
|
||
*
|
||
* row - An index in the GtkTreeView, i.e. the index of a row within the outward-facing API of the
|
||
* GtkFileSystemModel. However, note that our rows are 1-based, not 0-based, for the reason explained in the
|
||
* following paragraph. Variables/fields that represent visible rows are called "row", or "r_*", or simply
|
||
* "r".
|
||
*
|
||
* Each FileModelNode has a node->row field which is the number of visible rows in the treeview, *before and
|
||
* including* that node. This means that node->row is 1-based, instead of 0-based --- this makes some code
|
||
* simpler, believe it or not :) This also means that when the calling GtkTreeView gives us a GtkTreePath, we
|
||
* turn the 0-based treepath into a 1-based row for our purposes. If a node is not visible, it will have the
|
||
* same row number as its closest preceding visible node.
|
||
*
|
||
* We try to compute the node->row fields lazily. A node is said to be "valid" if its node->row is accurate.
|
||
* For this, the model keeps a model->n_nodes_valid field which is the count of valid nodes starting from the
|
||
* beginning of the model->files array. When a node changes its information, or when a node gets deleted, that
|
||
* node and the following ones get invalidated by simply setting model->n_nodes_valid to the array index of the
|
||
* node. If the model happens to need a node's row number and that node is in the model->files array after
|
||
* model->n_nodes_valid, then the nodes get re-validated up to the sought node. See node_validate_rows() for
|
||
* this logic.
|
||
*
|
||
* You never access a node->row directly. Instead, call node_get_tree_row(). That function will validate the nodes
|
||
* up to the sought one if the node is not valid yet, and it will return a proper 0-based row.
