[Buildbot-devel] svn_buildbot.py is generating an error on some commits

[Bailey, Darragh]

Doing some testing with sending commits that have been made to a subversion server by running the svn_buildbot.py script that is in the contrib folder manually.

For most commits that I was effectively forcing, the commit and details were sent along to the waterfall page just fine. But some would result in the following traceback being dumped to the console on the system that I ran the python script on to send the details about the change to buildbot.


quitting! because ([(False, <twisted.spread.pb.CopiedFailure exceptions.UnicodeDecodeError>)], 'SUCCESS')

Twisted is a little outdated on the sending machine, it's at 10.1 on the receiving machine. So will be trying an updated version of twisted just to eliminate the possibility that it's some bug due to changes in how data is being passed by the pb classes.

Hoping that someone else might already know what causes this type of error.
