I have put some additional information to my bug report which was marked as a duplicate of this one. https://bugs.kde.org/show_bug.cgi?id=432309 Mainly a very simple way to reproduce this issue (just 4 simple steps) and why it seems to crash (at least in my case).

Thanks for that, it gave more info/clues as to what was going south, (and actually the test in the merge request uses something similar). :)
