  * summary:  error changing raster legend settings => setting 'at=' to
              anything crashes raster legend

Comment:

 Now I know what's the origin of the problem: setting the 'at=' option to
 anything, e.g. '0,0'. The initial error is:

 {{{
 Traceback (most recent call last):
   File "/usr/local/grass-6.4.svn/etc/wxpython/gui_modules/gd
 ialogs.py", line 408, in OnOK

 self.parent.MapWindow.UpdateMap()
   File "/usr/local/grass-6.4.svn/etc/wxpython/gui_modules/ma
 pdisp.py", line 715, in UpdateMap

 for img in self.GetOverlay():
   File "/usr/local/grass-6.4.svn/etc/wxpython/gui_modules/ma
 pdisp.py", line 592, in GetOverlay

 if os.path.isfile(overlay.mapfile) and
 os.path.getsize(overlay.mapfile):
   File "/usr/lib/python2.5/posixpath.py", line 208, in
 isfile

 st = os.stat(path)
 TypeError
 :

 }}}

 The rest of the errors crops out when I press "OK" again.
