It seems that no one can reproduce this, although I haven't seen a
message from anyone running Ultrix 3.0.  Here is some more data to aid
in debugging.

Below is the output of a bash session where I tried to reduce my
environment to the absolute minimum.  Also included is the output of
"set" to show the environment.  It is interesting to note that it
didn't say "Bad command type" this time.
