Bugzilla is great, but you should _also_ target the maintainers directly 
and let them know.  And especially if you have bisected things, always cc 
everybody that is listed in the commit.

Otherwise, what happens is that other people not directly involved will 
eventually look at the regression list, and see it - but that generally 
happens much later. So things will get fixed from just the bugzilla report 
too, but you'll have a much longer latency than required.

In fact, if you can bisect it to a single commit (especially a small one 
like this), then bugzilla is the secondary, rather than the primary place. 
Bugzilla is great for keeping track of things and trying to avoid losing 
reports, but that comes at the expense of not being very convenient for 
short-term stuff.

So if you have a very targeted bugreport, and know who to send a report 
to, try the direct route first. Then, if nothing happens immediately, open 
a bugzilla (or open the bugzilla immediately, just in case, but see it 
as a "fallback" thing).
