[issue706] Backtrace when pushing to repo with diffstat hook

[Steve Borho]

New submission from Steve Borho <steve at borho.org>:

When pushing to a Linux box with a diffstat hook enabled:

[hooks]
changegroup = pull-diffstat

I get the following backtrace:

C:\hg\hg-release\.hg\patches>hg push
pushing to ssh://steve@trixy/tools/mq-win32-hg-plus

** unknown exception encountered, details follow

The push succeeded, regardless of the error message.  This seems to be
independent of the ssh client I use, and it happens whether I push a
normal repo or a patch queue repo.
