[Python-Dev] Buildslave gets intermittent errors in the svn step

[Paul Moore]

I'm getting occasional odd errors in the subversion step on my
buildslave (http://www.python.org/dev/buildbot/buildslaves/moore-windows):

Traceback (most recent call last):
  File "/data/buildbot/lib/python/buildbot/process/buildstep.py", line

    raise BuildSlaveTooOldError(m)
buildbot.interfaces.BuildSlaveTooOldError: This buildslave
(moore-windows) does not know about multiple branches, and using
mode=update would probably build the wrong tree. Refusing to build.
Please upgrade the buildslave to buildbot-0.7.0 or newer.

This is very odd, as (a) a simple rerun fixes the issue, and (b) I'm
already on buildbot 0.7.0 or newer (can't recall the exact version).

It's a Windows XP system, if that helps.

Does anyone have any suggestions?

Thanks,
Paul.
