Created attachment 83327 [details] New crash information added by DrKonqi plasma-desktop (4.11.2) on KDE Platform 4.11.2 using Qt 4.8.4 - What I was doing when the application crashed: using a second monitor, from time to time the panel on the second monitor crashes, and becomes overlayed over the panel in the first monitor, after some time i notice it, and have to removed sometimes multiple panels. In this case after removing all overlayed panels, and the unresponsive default panel on the second screen, i tried to add a new one, in which point there was a crash -- Backtrace (Reduced): #7 0x00007f76058a3b34 in QObject::connect (sender=sender@entry=0x67632c0, signal=signal@entry=0x7f75eb3183e9 "2destroyed()", receiver=receiver@entry=0x75c44a0, method=method@entry=0x7f75eb3183d8 "1widgetDeleted()", type=type@entry=Qt::AutoConnection) at kernel/qobject.cpp:2550 #8 0x00007f75eb3006af in SystemTray::Task::widget (this=this@entry=0x75c44a0, host=host@entry=0x63385e0, createIfNecessary=createIfNecessary@entry=true) at ../../../../../plasma/generic/applets/systemtray/core/task.cpp:80 #9 0x00007f75eb313e80 in SystemTray::Applet::_onAddedTask (this=this@entry=0x63385e0, task=0x75c44a0) at ../../../../../plasma/generic/applets/systemtray/ui/applet.cpp:196 #10 0x00007f75eb31424b in SystemTray::Applet::_onWidgetCreationFinished (this=0x63385e0) at ../../../../../plasma/generic/applets/systemtray/ui/applet.cpp:278 #11 0x00007f75eb314525 in SystemTray::Applet::qt_static_metacall (_o=0x67632c0, _id=-349076503, _a=0x7fff678608f0, _c=<optimized out>) at ./applet.moc:144

Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding! Nate Graham
