[Ubuntu] r.in.wms failing with GRASS 7.8.0

[Luí­s Moreira de Sousa]

Hi all,

the error message below is happening with GRASS 7.8.0 installed from the stable PPA on Ubuntu 18.04. It is a type mismatch exception from Python, happens with services from MapServer, all of which QGis can digest correctly. Could this be related to packaging? Or is it a bug with GRASS itself?

Thank you.

The above exception was the direct cause of the following exception:
