This used to happen with a few other apps on an old install, since then I
formatted and upgraded to the same system (Ubuntu breezy). The apps I had
problems with on that old install are working so I thought the problem was gone,
 but I just installed banshee and here's the same error again.
When I had problems with the old install I reported the bug here:
http://bugzilla.ubuntu.com/show_bug.cgi?id=14112

The problem only happens with the 'nvidia' driver (version 1.0.7667), 'nv' works
fine (xorg 6.8.2). Setting color depth to 16 instead of 24 appears to fix it
with the 'nvidia' driver.
