Comment 1 wolthera 2019-03-06 09:26:15 UTC 
this has a backtrace, so I'll confirm it.
Comment 2 Halla Rempt 2019-04-30 10:52:53 UTC 
I've seen this crash in the tile manager in a couple of other bug reports, but I am wondering whether wasn't fixed since the bug was reported, when Dmitry fixed other tile manager crashes. Dmitry, can you take a look at the backtrace?
Comment 3 Dmitry Kazakov 2019-04-30 11:40:48 UTC 
I think the bug should be fixed by my commit:
