Hello!
Today I made an update to QGIS 3.4.2 and now I can't use anymore the
GRASS commands in the toolbox The following python error message appears
when I try to open a GRASS command:
2018-12-10T16:00:28 WARNING Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: 'svn'
The GRASS plug-in is working (with GRASS 7.4.2). I am running a Windows
10 machine.
Does anybody know how to solve the problem?
Thank very much
Martin
