Description Michal Marek 2006-03-09 14:54:49 UTC 
Run hugin, select "Add individual images..." and close the file dialog again.
hugin either segfaults immediatelly or prints:


(hugin:17019): GLib-GObject-WARNING **: invalid uninstantiatable type `gchararray' in cast to `GtkFileChooser'

(hugin:17019): Gtk-CRITICAL **: gtk_file_chooser_get_filter: assertion `GTK_IS_FILE_CHOOSER (chooser)' failed

(hugin:17019): Gtk-CRITICAL **: gtk_file_chooser_list_filters: assertion `GTK_IS_FILE_CHOOSER (chooser)' failed

After two or three iterations, hugin eventually segfaults. Same result
on x86_64 and i586.

hugin-0.5-filedialog-close-crash.patch

Patch that avoids touching the dlg object when it's closed/cancelled.
The real problem is wxGTK not distinguishing between "dialog canceled" and
"dialog closed" (and the GTK widget free()d). It allways returns wxID_CANCEL :-(

Fixed. Could you report it upstream?
Comment 4 Michal Marek 2006-04-13 07:00:37 UTC 
done.
