           Summary: Plasma sometimes hangs when taskmanager-widget shows
                    tooltip
           Product: plasma
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: widget-taskbar
        AssignedTo: panel-devel kde org
        ReportedBy: kde stefan-neufeind de


Version:            (using KDE 4.0.4)
Installed from:    Fedora RPMs

For me plasma kept crashing 3-4 times a day during work. This appeared when changing tasks by clicking on items in the taskmanager-widget. (Is that called "taskbar" internally or "Task Manager" as it's shown in the UI?)

All open apps where still running, also still updating the screen or playing music etc. However I was unable to change any tasks, not even using the keyboard. Also clicking on the application-window of any task didn't focus it.

Changing to a text-console I was able to kill plasma (after unsuccessful trying to kill klauncher etc.). That didn't give me back access to a task-changer or so, but I was able to at least focus all open apps one after another and cleanly save my work before restarting KDE.


Workaround: Disabling tooltips in the the taskbar-widget-settings. That prevented any crashes (for more than a day now).

I found other bugs which I'm not sure are exactly related - but maybe: #161538, #161518.
