Comment 1 David Edmundson 2015-07-25 13:58:35 UTC 
Does this crash repeatedly?

It doesn't seem to be screen related; 

#9 0x00007f3445db863b in () at /usr/lib64/qt5/plugins/plasma/dataengine/plasma_engine_clipboard.so

The crash seems to be loading the clipboard history, possibly a broken entry there. Would love to see what that is.
