The file names are indeed different:

I see the same message without the '-l' flag and am a bit stumped about
where this comes from. In d.vect.thematic.py the only call to d.graph
happens if the '-l' flag is set, so this message do not seem to come from
the module itself. <wild guess>Could it be the wx0 monitor that tries to
call the file after d.vect.thematic itself has closed and erased its temp
files ?</wild guess>
