wxFilePickerCtrl crashes after multiple opening attempts

[bijwaard]

Dear sir, madame,

When opening a file via a wxFilePickerCtrl multiple times, the application crashes. Both my developed application, as wxformbuilder crash with the following error (debug trace attached):

(wxformbuilder:29400): Gtk-CRITICAL **: _gtk_file_chooser_entry_set_file_part: assertion `GTK_IS_FILE_CHOOSER_ENTRY (chooser_entry)' failed

(wxformbuilder:29400): Gtk-CRITICAL **: _gtk_file_chooser_entry_set_file_part: assertion `GTK_IS_FILE_CHOOSER_ENTRY (chooser_entry)' failed
**
Gtk:ERROR:/build/buildd/gtk+2.0-2.24.6/gtk/gtkfilechooserdefault.c:8751:gtk_file_chooser_default_initial_focus: assertion failed: (widget != NULL)
Aborted (core dumped)

This bug is similar to recent reports about the geany tool on x86_64, that crashes when multiple file-select attempts are done. The resolution (https://bugs.archlinux.org/task/25893) with geany was relinking with the updated libgtk2 libraries.

Reproducing the bug with wxformbuilder:
- open wxFormbuilder
- create a form with a wxFilePickerCtrl
- open the file picker and choose file
- repeat previous step about 5 times
- crash

Kind regards,
Dennis
