Comment 1 Martin Flöser 2017-04-02 09:04:27 UTC

Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install the debug packages provided by your distribution (please ask the distribution support channel on how to install them) and attach a new backtrace.

Comment 2 Keziolio 2017-04-21 15:26:34 UTC

I can't reproduce this crash any more, so I think this can be closed
