gnome-theme-manager image corruption

[Matt Brubeck <mbrubeck@cs.hmc.edu>]

Metacity theme preview image is currupted:
  http://bugzilla.gnome.org/show_bug.cgi?id=104837

I first saw this bug when gnome-theme-manager became part of the
gnome-control-center package a few days ago, but I hadn't reported it
because the latest upstream version of libmetacity hadn't reached Debian
yet.  Now I've upgraded to metacity 2.4.21 and the bug is still there.

This must be rare if it wasn't already reported, because it is very
obviously a bug.  Are any other Debian users seeing this?  I especially
want to hear from other Debian/powerpc users, because this seems likely
to be a bigendian problem.
