Anand: two things:
1) You guys should be building with symbols; not having symbols makes
your stack traces much less useful. Please pass that on to whoever is
doing build work for you. Thanks.
2) Was this when removing a panel? or when removing a pager? For me,
it occurred when I was removing a pager, not the complete panel.
George, Mark- don't know if that helps, but I hope so :)

This is a better stack trace, from CVS on 2/28.

note that there are similar bugs:
http://bugzilla.gnome.org/show_bug.cgi?id=72296 and
http://bugzilla.gnome.org/show_bug.cgi?id=73019, with their duplicates
and different backtraces.

As I can see, it happens when removing a panel which has pager on it,
or at least pager causes panel to crash.

It fails in a cast, so pager->pager does not exist or is corrupted.
And what's up with internal_size = -512?

Gedeminas: yes, I've seen that there are a number of things with
roughly similar cause, but they all seem to have slightly different
traces. Do you think I should mark them all as duplicates anyway?
