Bug#401871: Crash in gtk frontend when some languages are selected

[Attilio Fiandrotti <attilio.fiandrotti@gmail.com>]

package: cdebconf-gtk-udeb
severity: normal
tags: patch

Try booting a gtk miniiso at default medium priority and you'll be
prompted for language choice

-Select "Danish", then back to main-menu
-Select "Language Selection" , pick "English", then back to main menu
-Select "Danish", then back to main-menu

Now you should get a GTK frontend crash, which is easily avoidable with
the attached patch.
I wasn't able to reproduce this with NEWT frontend and  i even asked GTK
gurus [1] but no answer yet.
I could reproduce the crash with "Dansk" and "Dzongkha" languages only
and this does not help at all at making light on its roots, so i would
suggest to wait some more before applying this patch.

cheers

Attilio
