Comment (by neteler):

 Replying to [comment:1 annakrat]:
 > Does this happen in any location?

 No, see below.

 > What does g.mapsets -l return?

 It returns a list of mapsets, all exist.

 > I don't see anything problematic and it works here, so you would have to
 investigate what it is trying to remove in core/utils.py L308.

 Ok, this helped to debug the problem:

 The actual mapset lacks the `WIND` file:

 {{{
 g.region -p
 ERROR: Unable to open element file <> for <WIND at ortsteil_1>
 }}}

 I have no clue how this happened but I thought we had an "auto-repair" in
 place somewhere (like we do for the `sqlite/` subdir).

 A possibility might be to catch such an error (earlier) and reject to
 start GRASS with a broken mapset.
