[Dune-devel] Python tests fail but changes are unrelated

[Christoph Grüninger]

Hi Simon,
hi Andreas,

thanks for your feedback! I opened an issue in dune-common, to have one 
place to discuss.

https://gitlab.dune-project.org/core/dune-common/-/issues/295

The bug Andreas dug out looks promising.

Bye
Christoph
