[Bug 35520] gconf-editor crashes adding string to list

[Craig Box]

Public bug reported:
https://launchpad.net/malone/bugs/35520

Affects: gconf-editor (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I am having a problem adding info to a list on a gconf key.

Steps I used to cause this fault:

1. Open gconf-editor
2. Navigate to key /apps/compiz/general/allscreens/options/
3. Double click "active plugins" (notified in the background window that this key has no schema)
4. Hit 'add', type in 'transset', click OK, click OK again to close list window.
5. Double click the 'active plugins' list again and notice that transset was not added.
6. Add it again, click OK to close list window, program crashes.

** ERROR **: file gailtreeview.c: line 3604 (garbage_collect_cell_data): assertion failed: (GAIL_IS_TREE_VIEW (data))
aborting...

Program received signal SIGABRT, Aborted.
