gnome-terminal is a default terminal for Gnome as you know. That means
that not only I, but most Gnome would have to do it. This means that
d.m in Grass 6.3 will be broken on many Linux boxes by default. If we
don't want it, shouldn't the change that breaks Grass 6.3 on Gnome
should be reverted?
What was wrong about using xterm by deafult?
Programs which require a terminal should arguably use the user's
preferred terminal by default. Of course, that reasoning falls down if
the user's preferred terminal is signficantly broken.
Have you checked whether this is an actual gnome-terminal
bug/misfeature, or whether it's just your configuration that's causing
problems?

It appears that gnome-terminal resets $PATH.
In which case, you need to either set GRASS_XTERM to "xterm" to force
the use of an xterm instead, or figure out how to make gnome-terminal
preserve $PATH.

I can confirm the problem, and up to now, I have not been able to find a command switch to gnome-terminal which allows to keep environment variables...

I can confirm the problem, and up to now, I have not been able to find a
command switch to gnome-terminal which allows to keep environment
variables...
In which case, grass-xterm-wrapper should simply set GRASS_XTERM to
"xterm" if it isn't already set, and not attempt to use
x-terminal-emulator.
If the user wants to use x-terminal-emulator, they'll need to set
GRASS_XTERM themselves, and ensure that their chosen program works.
GRASS uses environment variables extensively; a terminal emulator
which clears the environment is essentially detaching itself from the
GRASS session.

OK, I have simplified this now to:
################ snip ##############
#!/bin/sh
# script to wrap xterm
if [ -z "$GRASS_XTERM" ] ; then
GRASS_XTERM=xterm
fi
# run command
exec $GRASS_XTERM "$@"
########## snap ####################
