Bug 198276

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.93 (KDE 4.2.93 (KDE 4.3 >= 20090623)) "release 1"
Qt Version: 4.5.2
Operating System: Linux 2.6.25.20-0.4-pae i686

What I was doing when the application crashed:
After an hour or two of normal use ( listening music with amarok, browsing internet with firefox, writing with kword ), plasma start crashing. After the first crash it reload and then crash again, and never stop crashing until i reboot or log out
