Bug#763602: Backtrace for "Crashes on startup with "Attempt to unlock mutex that was not locked""
Okay, this seems to be a bug in Python?
There is also a very similar issue with reportbug at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=758619 but that
doesn’t have an immediate solution either.
(Backtrace from gdb below)
Best,
Claudius
