> What version of Gtk+ do you have?  Are you using some Gtk-qt theme?

report-emacs-bug tells me it's: In GNU Emacs 22.0.92.34
(i686-pc-linux-gnu, GTK+ Version 2.8.20) of 2007-01-08 on trpaslik.

dpkg tells me:

||/ Name           Version        Description
+++-==============-==============-============================================
ii  libgtk2.0-dev  2.8.20-3       Development files for the GTK+ library
ii  libgtk2.0-0    2.8.20-3       The GTK+ graphical user interface library

I'm using a theme called "Clearlooks" in GNOME on debian sid.  I think
it's one of the default GNOME themes.  When I first reported this bug,
I hadn't ever installed KDE or anything QT-ish on this machine,
although I have done since.

Chris.
