Thanks!  

The patch *looked* correct, and it was pretty obvious, so I don't
entirely blame you for not running tests --- but it's why I tend to
run smoke tests regularly when merging in patches, and I do encourage
folks to run the smoke test for any patch, no matter how simple.  Yes,
it takes 30 minutes, but it's worth it.

I suspect there may be some underlying bug which your patch unmasked,
so it would be good for us to understand why it caused the failure.
