Works for me on Linux with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041107 Firefox/1.0.  FWIW I'm using icewm...

I've been trying to narrow down the problem. It occurs for me in gtk2+xft builds
of mozilla and was fixed sometime between 1.8a4 and 1.8a5. It also seems to be
fixed in the latest firefox trunk builds.
