bitten-slave suddenly stops working and returns a 404 error

[pfote@…]

we had the effect that a working configuration suddenly stopped working, bitten-slave returned something like:

bittenslave@dev1:~$ bitten-slave -v -f slave.ini http://trac-host:8000/builds

it turned out that a changeset was not found in the git repository:

however, that changeset DOES exist in the repository.

we're running bitten 0.6b2 on the following trac (debian lenny 5.0.4):

Trac:	0.11.5
Python:	2.5.2 (r252:60911, Jan 24 2010, 14:53:14) [GCC 4.3.2]
setuptools:	0.6c8
SQLite:	3.5.9
pysqlite:	2.3.2
Genshi:	0.5.1
Pygments:	1.1.1
Bitten:	0.6b2
GIT:	1.5.6.5
jQuery:	1.2.6

unfortunatly i'm not able to offer you guys the repository in question for reproduction, but i'm willing to test patches

Exiting slaves is a problem here too. Bitten slaves should have an option to report by email when they fail and exit.
