Comment 3 for bug 240337

I'm having the same problem with Firefox 3 on Kubuntu 8.04. Also seems to be related to ESD. If I start FF in GDB and break it during the "hang" I get this backtrace:

FF2 works fine. FF3 worked fine when I first installed the initial release of 8.04 (actually I think I started with a beta) but an update about 3 weeks ago broke it.
