In this particular case, I could not enter the location via the GUI 
startup, but had no problem using it via the text startup.

There is the same kind of test for mapsets (lines 499ff and 650ff):

               if {[file exists "$database/$location/$mapset/WIND"] == 0} {
                     DialogGen .wrnDlg [G_msg "WARNING: invalid mapset"] 
warning \
                     [format [G_msg "Warning: <%s> is not a valid 
mapset"] $mapset] \
                     0 OK;
                 }
if { $mapset != "" && [file exists "$database/$location/$mapset/WIND"] 
!= 0} {
                     puts stdout "GISDBASE='$database';"
                     puts stdout "LOCATION_NAME='$location';"
                     puts stdout "MAPSET='$mapset';"
                     putGRASSRC $gisrc_name
                     exit 0
                 }
             }


Again, should a missing WIND file be a reason to fail entering a mapset 
? I think gis_set.tcl should just silently copy PERMANENT/DEFAULT_WIND 
to $mapset/WIND ?
