In between now and the last time I sliced a model I updated my operating system (OpenSuSE). Now, the repo version of cura-lulzbot won’t slice my models. On run it fails when trying to import Savitar (see log at 2 below), although the package is installed and can be imported at a commandline (see 1).

Any ideas on how I might resolve this?

Thanks

Brendan

1. Is Savitar importable?

So, apparently importing Savitar before pyqt5 eliminates the import errors:  
https://github.com/Ultimaker/Cura/blob/b20a349b4454d08e34b3c3ea3f537a380e4c7696/cura\_app.py#L140-L141

Unfortunately, does not solve the problem in that it continues to fail to slice - it says it’s slicing, but it never finishes.
