Editor: changing Level or Reputation of an NPC crashes the editor

Please test! Start OpenMW-CS > new addon > menu: world > objects > edit NPC > change "Level" or" Reputation" -> this gives me a core dump.

I have no clue how to make gdb show somewhat useful. I tried 'cmake -DWITH_DEBUG=1' but that didn't help at all - except: execution is noticeable slower when the CS reads data from the Morrowind/Tribunal/Bloodmoon-'file'.
