[Buildbot-devel] 0.7.11 regression?

[Marijn Vriens]

Hi all,

Switched a slave to buildbot 0.7.11 and I got the traceback below.
"easy_installing" back to 0.7.10p1 seems to fix it. Machine is a ubuntu 9.04
running on AMD64, buildbot is running in a virtualenv.  The master is still
running 0.7.10p1.

As I can read the logfile, the build dies at the first step:

from buildbot.steps.source import Mercurial
f1 = factory.BuildFactory()
hg = Mercurial("http://protocultura.cl/hg/steward/", mode="export")
f1.addStep(hg, description="Updating", descriptionDone="Updated")

The traceback from slave/twistd.log is:

2009-07-12 16:40:13+0000 [Broker,client]
SlaveBuilder.remote_ping(<SlaveBuilder 'steward-py2.6' at 18400392>)

receive following PB traceback:
