I'm confused.  You pointed to the build I did this morning, which
definitely doesn't include the commit you mentioned.  Are you saying you
took this morning's build and applied the patch yourself?  If so, did it
really get applied?  Do you have logs?  Do you have more than just that
tiny snippet of error message?
