If it occured suddenly, you can try to reset the configuration with the button in the preferences. Another possiility is to delete your config files or to move them in case you want to restore them.

Chris, this won't help. The freecad-stable PPA is currently broken on Ubuntu 18.04 and 18.10.

Sorry I had seen the topic but did not follow it further . Glad I added the part with moving the config files.

[aubiwan]

"chrisb" thank you for your answer, I have tried to remove cfg files (user.cfg and system.cfg) but I have still the same crash on activating draft workbench.

I am having the same problem.

A little bit more context.

I installed all dependencies to compile master (it was working) and now both 0.17 and master (from sources) give this error:

This also happens on 0.18 under Debian Buster, but in this case when a new sketch is createdusing the part design workbench .

Any clues? I have tried by deleting the configuration folder, but no luck.
