The problem is caused by gtk_im_multicontext_set_slave(), which forgets to disconnect these signal handlers: * gtk_im_multicontext_retrieve_surrounding_cb * gtk_im_multicontext_delete_surrounding_cb If slave GtkImContext emits signal after GtkIMMulticontext context is destroyed, this leads to reading freed memory, sometimes causing a crash. Fixes: #2365
