I've had this error (in fact, I think I have committed almost all errors!),
and it comes about when you are interactively calling the routine from
the command line during a session (or running main level scripts) and
the keyword is defined as you repeatedly call the routine. Then
when you leave IDL, and go back in, the keyword is undefined again
and it could behave differently than expected.

Cheers,
bob

PS I almost always run main level scripts in the windows version.
and during development one can trip over persistent main level
variables.
