Comment (by gjznituv at gmail.com):

 I'm on Leopard, 10.5.1.

 I haven't installed the X11 update. Should I? Or is that something that
 breaks gtk2?

 My $DISPLAY may have gone awry:

 {{{
 [~] echo $DISPLAY
 :0.0
 [~] /tmp/launch
 launch-1kcZ0I/       launch-Zf7Gla/       launchd-213.s2eVAU/
 launchd-59.kte9k3/
 launch-5QOTXc/       launchd-129.Duln8W/  launchd-216.PGV2fl/
 launchd-6782.JEBM94/
 }}}

 What should I do about it?
