[Arne Caspari]

Public bug reported:

Affects: gtk+2.0 libgtk2.0-0 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
The GTK file dialog seems to block forever under the following
condition:

- Have a bookmarks for  a SMB network share in the dialog
- Have the keyring unlocked and the SMB share accessible ( eg. via nautilus ). 
- unplug the network cable
- start GEdit and select 'Open' or 'Save'

--> The application will deadlock

Deactivating the network interface or reconnecting the cable will bring
back the application.
