Installed from:    Mandriva RPMs

Whilst working normally on the kde desktop sometimes (and its becoming more frequent) the plasma task pane crashes and causes this error.  It automatically reloads the task pane.  However all subsequent clicks result in the task pane disappearing and reappearing until the pane doesn't auto restart (then use task runner to get it back) but it just keeps crashing with me clicking on the start menu.  In fact I don't think I've been able to get the menu to show at all since this started happening, I've just been clicking on the task pane firefox shortcut and running everything else from task runner.  I've included the error text below:
