Were you able to reproduce this at all? Has this happened since?

> Were you able to reproduce this at all? Has this happened since?

I tried again, but could not reproduce this crash.
Comment 3 Martin Klapetek 2015-05-13 14:34:02 UTC 
We now require Qt 5.4 for Plasma, this report is using Qt 5.3. 

If this problem still occurs with Qt 5.4 (and Plasma 5.3), please reopen this report.

Thank you
