It was RT issue 3306 from May 24.
Two days later I managed to catch a proper Backtrace of the crash, which I uploaded to
Filebin.
But noone seems to have taken care of it; it has not been labelled this or that.
What is the normal procedure in cases such as this?
Post the backtrace or a link to the githib page!
Yes, I did that on May 26. Quote:

@Claes: It’s holyday season right now, so don’t expect too much reaction this month. 
I had a look at your backtrace: It should help to nail down the problem. I think I’ve tried to reproduce your problem, but was not yet able to. I don’t have the sources with me, nor a powerful enough laptop to try it, but I’ll come back to your issue, as soon as I’ve returned. In the meantime: If there is anything else that could help us to locate the crash, please add it to the github issue. Thanks.
