Description Christian Persch 2005-03-02 13:35:47 UTC 
Steps to reproduce:
0) Tools->Page Info
1) Visit the Media tab
2) Close the dialogue

Warning on console:

This is likely due to the fix for bug 167259. I'm going to look if this is due
to gtkmozembed doing something evil in unrealize, or if it's gtk+' fault.
Comment 1 Christian Persch 2005-03-02 14:39:03 UTC 
Re-assigning to gtk+ and attaching testcase.

GtkMozEmbed is as GtkBin which reparents its child to an (offscreen) GtkFixed on
unrealize.
