[Denemo-devel] Denemo crash on startup

[Andreas Schneider]

Hi,

after updating to the newest version from git, Denemo crashes with a
segmentation fault on startup (after having said No to the question
whether to re-use existing commands, shortcuts, etc.), see the traceback
below. Do you have an idea what might cause that? My OS is Debian
Stretch (9.6).
