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"
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. *** This bug has been marked as a duplicate of bug 344942 ***
