I have submitted the following bug upstream:

https://fedorahosted.org/revisor/ticket/375

...but it looks like the "revisor" package has been abandoned, and
that Scientific Linux maintains its own set of bug fixes.

Any chance I can convince the SL maintainers to adopt my (one-line)
bug fix?  Of course I can create my own version, but having it in
SL6.x would save me a good deal of headache in the future.

Thanks.
