I'm not entirely sure what the problem is, but assuming \n is the line separator seems like a good place to start.

This also fails on my linux vm.
I'm using hg 1.9 on osx, 1.8.3 on linux, 1.8.1 on windows; maybe that's it?

Comment 2

[Aki Sasaki (not active)]

[cltbld@localhost ~]$ hg --version
*** failed to import extension share: No module named share
Mercurial Distributed SCM (version 1.1.2)

I wonder how I got 1.8.3 ?

This would explain the error.

Comment 3

[Aki Sasaki (not active)]

N/m, retried with a new virtualenv and hg 1.9.1 on linux.
Still getting this error.
Tempted to follow Rail's advice and just use the mercurial python module rather than using hgtool, since I don't fully understand what I ported.

Comment 4

Sadly, this was the canary that should have prevented me from landing 0.4.

I didn't realize this would cause production mozharness issues, as I hadn't explicitly turned on hg sharing in any mozharness functionality.
However, the backwards compatibility with hgtool meant we picked up hg sharing automatically in multilocale builds, hence bug 691161.

The patch I'm going to submit to bug 691161 will also fix this bug.
