Comment 2 Pavel 2016-11-18 13:39:19 UTC

I think that not the same/duplicate error. Yes, I know if you are take a look to the trace-code it's the same. But I have this error not after change theme from one to other, I take this error, when I try to goto inside one menu, and next goto some other menu position. Additionally if I goto inside "Hardware" menu and check menu position 1, and after some time (I do nothing in this menu) just goto other menu position in "Hardware" category, everything work's fine. I found these two error's just in described two position's:

1. from "Appearance -> Application Style -> Window decorations" goto "Appearance -> Application Style -> GNOME (GTK) Application Style"
2. from "Workspace -> Desktop Effect -> Screen Lock" goto "Workspace -> Desktop Effect -> whatever other menu position"

Comment 3 Christoph Feck 2016-11-21 03:27:08 UTC

Please do not change the bug status. The crash is in Qt's V4 JavaScript engine, and is caused by the use of QML in some systemsettings modules.
