Re: Plasma crash on unlock widgets

Sat Sep 17, 2016 11:09 am
I have exactly the same problem on 5.7.5 on Arch with Intel drivers, other things also crashes a lot. Like when I am deleting files in dolphin.
I noticed that it is always about libQtGui.so.4 when application wants to create a new window (QWidget I suppose). I reinstalled qt4, but no luck. Maybe it is like the library needs to be recompiled or something.

#5 0x00007f6440978b74 in ?? () from /usr/lib/libQtGui.so.4

EDIT:
I removed kdegraphics-okular which had a dependency on qt4 and I am no longer experiencing crashes. I guess I need to report that to Arch guys.
