This has been my experience too.  I found a user comment explaining this
on the "gtk 2.2 released!" page on the www.gnomedesktop.org news site:
apparently gtk 2.2 closes a bug that gnome 2.0 was relying on.

Solutions: upgrade to gnome 2.1.x or higher, or downgrade to gtk 2.0.
I'm going to downgrade to gtk 2.0 for now and then move up to
gtk and gnome 2.2 at the same time.

I don't have any current plans to require gtk 2.2 for Pan either. :)

cheers,
Charles
