Bug 194669

Version:            (using KDE 4.2.3)
Installed from:    Fedora RPMs

Plasma just crashed as I was clicking the pager applet after I had added and removed some widgets from the desktop (and the taskbar). I know this is not really reproducible, but I mainly post this in order to have a place to post the stacktrace. Maybe that helps. Seems like the crash happened while swhitching the focus to the pager applet.

Application: Plasma Workspace (plasma), signal SIGSEGV
