I don't know if this is the same bug or not but in a Samsung NC10 netbook running arch linux with plasma next and the kf5 packages installed after uninstalling all old kde 4 packages, I can log in to the plasma next desktop but if any attempt is made to add widgets to the desktop (after unlocking widgets) the list of widgets pops onto the screen, but after a few seconds there is a plasmashell crash, with a recovery of the desktop without manual intervention. This occurs whichever of kicker or kickoff is in place using alternatives. Any attempt to send a crash report with a backtrace gives a message that there is no useful information in the backtrace. After updating to 5.2 today from the arch repo the same symptoms occur and this happens every time adding widgets is attempted completely consistently.
Created attachment 91216 [details] Test Case I have same problems. I've attached simple test case which can be compiled with following qmake .pro file. TEMPLATE = app CONFIG += c++11 QT += widgets SOURCES += main.cpp
still valid for plasma 5.2.1, KF 5.7 and Qt 5.4.1 normally now plasmashell crashes only few seconds after widgets-sidepanel opened
@Robby Engelmann: Can you please attach new backtrace? or is it similar to previous one? I think crash on opening widget sidebar is not related to previous one..
I think, it is the very same bug, as plasmashell earlier crashed on opening and scrolling through the wigdets. However, I will try to get a new backtrace...means installing debug symbols and hoping, that my cpu will survive (last time it took almost 15 mins at max cpu to get one :-) )
is there an easy way to get all necessary debug symbols installed in opensuse tumbleweed? Last time I installed simply all for plasma5 KF5 and Qt5.
Well first you can get backtrace without debug symbols; also I think drkonqi allows you to install required debug symbols; in anyway.. please give backtrace here even without debug symbols if you have.

Do you have systemloadviewer applet available on your desktop? if yes thats duplicate of https://bugs.kde.org/show_bug.cgi?id=345141
correct, marked as duplicate *** This bug has been marked as a duplicate of bug 345141 ***
I have been tracking this bug for a while - on my own Samsung NC10 netbook, running arch linux, with current latest kf5 and plasma packages without any old kde packages this bug was always present. I have always had the systemloadviewer applet on the desktop as the only applet present. After seeing comment #9 I removed the systemloadviewer applet and tested again - there is no longer a crash when opening the add widgets left hand menu, even after multiple scrolling up and down looking at available widgets. This is possibly related to https://bugs.kde.org/show_bug.cgi?id=345141 My system is single core (Atom) processor.
