Version:           4.1.2 (using KDE 4.1.2)
OS:                Linux
Installed from:    Mandriva RPMs

Occurs randomly when left-clicking on the Application Launcher icon in the Task Manager bar.  Mostly with the first mouseclick after a fresh boot.  Usually recovers on its own, although seldom completely, and sometimes the Application Launcher widget doesn't reappear.  Can occasionally force a crash by changing menu styles (kickoff, classic) and then clicking on the new widget icon.  Once or twice the PC has had to be rebooted using the PC front panel RESET switch.

Mandriva RPM package ID: kdebase4-workspace-4.1.2-13.3mdv2009.0

File: /usr/bin/plasma: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
