Playing around with raster legend settings in wxGUI I got a following
error. Can't tell the exact way to reproduce.

#289: setting 'at=' to anything crashes raster legend

  * 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

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.

Comment:

This was fixed in recent improvements to overlays. I just tested it and it
works fine.
