[Win] Buildbot cannot trigger a manual build on Windows

[Brent Fulgham]

Any time we request a manual build on a Windows build or test bot, or when we restart a Windows buildbot and new patches are not waiting in the build queue, we get the following error:

starting svn operation
/usr/bin/svn update --non-interactive --no-auth-cache --revision 164249
 in dir /home/buildbot/slave/win-release-tests/build (timeout 1200 secs)

 argv: ['/usr/bin/svn', 'update', '--non-interactive', '--no-auth-cache', '--revision', '164249']
error in RunProcess._startCommand

    msg += "  %s=%s\n" % (name, self.environ[name])
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 145: ordinal not in range(128)

This does not happen on our Mac or Linux platforms. It seems to be a Windows-specific Python or buildbot bug.

It looks like this only goes away after a reboot. Maybe the act of shutting down the build slave and restarting it doesn't clean up properly?

@Fuji & @Don - Is this applicable for 'win-cairo' bots? Or we can mark this as 'RESOLVED CONFIGURATION CHANGED' since AppleWin is gone now.

Think we can resolve this
