As I suggested earlier, you need to find the shell code
(probably bourne shell code) that your window manager is running
before it exec's xterm. You'll probably find a trap stmt there.

That's the way it should be.
So your login shell is clean,
but window-manager-spawned tools get the bad environment.
You haven't said what window manager you're using, but each one
usually comes with plenty of start-up scripts (usually under /etc).
Search those for the trap.
