Thank you for reporting this!  Fixed in commit b1a102d[0].

Also thanks for submitting a patch.  However, would I have seen it in 
the commit log I'd probably have raised a stink :-)

Upstream hash mismatches should be rare and treated with some suspicion. 
  The hash wasn't *incorrect* (hence, not a ‘fix’) when libjpeg was 
packaged—it was *changed*.

I think it's our responsibility to log these changes in the commit log, 
even though they are benign.

Well, obviously they are benign.  We'd probably not commit them if they 
weren't.

Probably.

Closing,

T G-R
