Crash on rendering

Too often merkaartor crashes at:

Merkaartor 0.19.0 Qt 5.15.3

Not much info in that stacktrace. Can you:

  1. Narrow that to a specific action sequence/geographic area/rendering style?
  2. Build merkaartor from source (preferably git master) with debug symbols and post a stacktrace for this build?

Meanwhile, i will try to reproduce on my own, but I did not encounter any crash when testing 0.19.0.
