Description Felix Berger 2005-10-30 15:29:28 UTC

Version:            (using KDE KDE 3.4.2)
Installed from:    Debian testing/unstable Packages
OS:                Linux

I don't exactly remember what I was doing when kwin crashed, but it always happened when a swing dialog was open and I closed it or maybe tried to focus the dialog underneath... Here's the bt:

Sorry, but I need a testcase to reproduce this problem, just the backtrace is not enough.

Yes, please I see this too.. Any news?  I'm running p4, with Fedora core6.  This seems to happen randomly with my swing application.  It can run fine for an hour opening and closing dialogs, but then suddenly either opening or closing a dialog will crash kwin.  I'm not sure how to safely kill X, so I'm stuck rebooting.
