 Hi,

 if I do "chmod 999.999 $LOCATION/user1" to make my user account not the
 owner of a mapset, and then start grass with the full path to the mapset I
 get this error:

 {{{
 Cleaning up temporary files ...
 Starting GRASS ...
 $LOCATION/user1/.gislock: Permission denied
 ERROR: $GISBASE/etc/lock:
 hb is currently running GRASS in selected mapset (file
 $LOCATION/user1/.gislock found). Concurrent use not allowed.
 }}}


 user1 is drwxr-xr-x, so the Permission denied comes from the fact that
 etc/lock can't write the .gislock file, not that my current user account
 already has a copy there. (I checked, the file doesn't exist)

 So that Permission denied needs to be better caught I guess.
 or improve  G!__mapset_permissions() or G!__mapset_permissions2() and it's
 a case of the error message being a bit too overenthusiastic?


 if I start GRASS with -tcltk the mapset is simply missing from the list
 (greyed out would be nicer if $MAPSET/WIND exists but we don't own it). I
 don't have wx on this machine to test the wxGUI startup, nor did I test
 changing mapsets with g.mapset. And no idea what happens if you force the
 mapset change with g.gisenv.
