I have tried here on Mandriva 64bit


GRASS 6.5.svn (patUTM32):~/grass65 > g.gisenv set=DEBUG=5
GRASS 6.5.svn (patUTM32):~/grass65 > g.gui wxpython
D1/5: Attempting to start 'wxpython' GUI ...

Same thing - old map appears, disappears and that's it.

I see it only in wxgui.py:

Index: wxgui.py

Unfortunately it does not help.
I see http://trac.osgeo.org/grass/ticket/594
which seems to be related.

Perhaps some more magic is needed (bad URL with spaces)?
