Comment 1 Martin van Es 2009-07-07 13:47:11 UTC
I also experience frequent plasma crashes (segfault) since upgrading to RC1 (kubuntu 9.04 packages). I don't know if these are ff3.5 related, but I use that as well. The backtrace is not usefull according to the dialog, so I didn't save it. The dialog is shown only once per session, all the other crashes happen silently in the background.
I removed all widgets from the Desktop, but that didn't help.
I use compiz as a window manager.

> I don't know if these are ff3.5 related

To be honest, I don't think Firefox 3.5 has anything to do with this crash, too. But it was the only "abnormal" thing I was doing when the crash happened - so I put it in the report. I wasn't able to reproduce this since the original report.
Comment 3 Martin van Es 2009-07-08 18:14:43 UTC
I think I've found the (or at least my) problem, revealed by the attached backtrace. For some reason I had the taskmanager group and sort applications (which is not what I needed, but maybe some default?). After disabling grouping and sorting I have not seen another plasma crash.
