Comment:

 just another data point:

 I can reproduce this in 6.4 and 6.5, but I have to try for a minute or two
 first (it's on a rather fast machine, which may help, although I am
 running X tunneled over ssh from it). I got no error message when the
 wxGUI was launched automatically at startup.

 I notice that draging the toolbar is not the most responsive thing once a
 map is loaded. I had to try harder in 6.5, but that might just be chance.

 Running same Debian/stable (lenny) amd64 with python-wxgtk2.8 version
 2.8.7.1-1.1+lenny1 and python 2.5.2-3.


 Also I notice that if I remove or uncheck everything on the list the last
 map standing does not clear from the display window. If I press the erase
 button, the image comes back after I tear-away or reconnect the display
 toolbar.

 I suspect that this is an upstream bug, and there is little we can do
 about it.. but no idea.

 wow, I just restarted grass in text mode and then g.gui from the command
 prompt, and it died after adding a raster map and then a vector map with:
 {{{
 (hamish:10965): Pango-CRITICAL **: pango_break: assertion `attrs != NULL'
 failed
 (hamish:10965): Pango-WARNING **: shaping failure, expect ugly output.
 shape-engine='BasicEngineFc', font='Bitstream Vera Sans 9.9990234375',
 text=''
 }}}

 maybe I should try restarting X now..
