qb crashes while creating a new folder in RSS Downloader dialog

[xtro]

I using Ubuntu 10.04. I just wanted to create a new download rule in the RSS Downloader module. While creating a new folder under "Rule definition -> Save to a different directory -> Safe to:" the program crashed with the following output:

(<unknown>:30048): Gtk-CRITICAL **: _gtk_file_system_model_get_iter_for_file: assertion `G_IS_FILE (file)' failed
**
Gtk:ERROR:/build/buildd/gtk+2.0-2.20.1/gtk/gtkfilechooserdefault.c:6687:file_system_model_set: code should not be reached

The ASSERT is in gtk+2.0 code and I believe my code is correct. This is likely to be a bug in gtk+2.0
