Richard Moe Gustavsen 0857db89bf Widgets: check if parent exists before calling parent->locale()
If a top level, parentless widget has Qt::WA_WindowPropagation
set, Qt will crash when trying to resolve the widgets locale.
The reason is that we try to access the QLocale of the
non-existing parent.

This patch will add a check if a parent exists before trying
to access it.
