[Bug 28640] GTK2 apps crash when browsing a directory with UTF8 filenames

[Billy Kwong]

Public bug reported:
https://launchpad.net/malone/bugs/28640

Affects: glib2.0 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Whenever I browse in any GTK2 apps to a directory with UTF8 filenames,
the app would segfault. (So far, beep-media-player and nautilus does
this)

I have provided a backtrace from beep-media-player for your reference.
Beep crashed when I was in the GTK2 file dialog into said directory.
