Windows updates OK from the first build today, need to check Linux. We've disabled updates on Mac to prevent any further people from updating to broken builds.
When we apply an update we use the updater.app from the existing build, so the regression window is
Fallout from bug 680440 changes ?

Linux shouldn't be affected because libmozutils is statically linked in the binaries, there. On Windows, the updater is most probably in the same directory as the library, which makes it not be a problem. On mac, it appears the updater is in a separate directory, for a reason I ignore, so it can't find the library in that directory.
Two possible fixes here: changing the link path to libmozutils for the linker to be the right one, or not linking the updater against libmozutils at all, since it really doesn't need it. I'd go for the latter.
I guess this also means our updater tests don't use the final paths on mac, and failed to catch that error... :-/

Avoid linking the updater against libmozutils
This made it into the latest nightly, so I've re-enabled Mac Nightly updates.

Since we got a dupe, I blogged to help out the ~350 people stuck on busted builds:
fwiw, I had been experiencing the updater crash every day since 9/19. Yesterday, I installed the new baseline nightly build (from comment #9) and today a new nightly update was detected and installed without any crash. thanks!
