[SOLVED] Cura errors after upgrade when importing models

nnscr · 2017-09-16 08:49:10

Hello,

after the latest upgrade of cura through pacman I get python errors when importing a STL model. Gcodes work, but STL fails. I already tried reinstalling cura and all dependencies, resetting the settings etc. This is the error I get:

2017-09-16 10:46:08,959 - CRITICAL - cura.CrashHandler.show [42]: AttributeError: 'NoneType' object has no attribute 'getMinkowskiHull'

Has someone experienced this already? Is there a known workaround?

Thanks!

Related? https://bugs.archlinux.org/task/55609

No, it doesn't seem to be related. The error message is different and the workaround doesn't work. Plus it starts for me and doesn't crash, in that bug report cura doesn't even start.

Okay, I've noticed that it works with a fresh install on my laptop. So I've traced down the problem and deleted the

~/.cache/cura

directory. So everything workings again!
