QGIS » QGIS Application

Dear devs,
first of all a huge thank you for the rework of the processing framework for qgis3 - it is promising huge improvements!
Unfortunately I ran into a bug that breaks the script collection plugin functionality for me while I was porting such a plugin from qgis2.x to qgis3. The problem still exists when I populate the plugin with the scripts from the current on-line scripts collection and throws a GUI-related python error.

Is this bug replicable for you?

I suppose that the script collection plugin might trigger some other python errors besides this gui-related error due to the rework of processing - just a guess.

I will paste the stack trace and my path-vars here for reference, if you need more information from me don't hesitate to ask!

Thanks!
