Comment 23 for bug 548652

I found that this issue is related to the theme being used. On the machine with problems I usually use Fedora with Echo icons. When I tried using Bluecurve (with or without Echo Icons) I didn't see the problem. Switching back caused it to reappear.
I need to check to see if I have a corrupted install of that theme and whether or not the same problem is visible on a couple of other machines. (I typically don't mess with the theme on my scratchish machines, so they are probably using Bluecurve.)
