Error when executing HRU intersection

An error has occurred while executing Python code: 

KeyError: NULL 
Traceback (most recent call last):
  File "C:\Users/felixfroehlich/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\QTalsim\qtalsim.py", line 1561, in performIntersect
    sum_areas[ezg] += area
KeyError: NULL

trying again with both "Minimum ..." options deactivated causes a different error:

An error has occurred while executing Python code: 

_core.QgsProcessingException: Could not write feature into OUTPUT

Maybe the above errors were due to one of the input layers being in a different coordinate system?

I tried again with all input layers already cleaned (no gaps or overlaps) and all in the same CRS, but then QGIS completely crashes after processing for a while.

Bug fixed with commit f42d166. Fix is released in QGIS with V1.3.1.
