We figured it out: The user, by mistake, added a mapset with trailing "/":

Here an example

GRASS 7.0.0svn (eu_laea):~ > g.mapsets nightdata_new/ operation=add
GRASS 7.0.0svn (eu_laea):~ > g.mapsets -p
Accessible mapsets:
neteler PERMANENT modis_lst_reconstructed_europe_monthly nightdata_new
nightdata_new/

This will (maybe not surprisingly) crash the GUI at the next startup.

Question: is there a way to chop off such "junk" chars? Can we use
G_legal_filename() here?

thanks
