Version: (using KDE KDE 3.5.1) Installed from: Unlisted Binary Package I click on the Show desktop applet, then click it again and then sometimes the window borders (kwin) and kicker are gone. I got this backrace: (no debugging symbols found) Using host libthread_db library "/lib/tls/libthread_db.so.1". (no debugging symbols found) `system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
