TypeError in buildbot.slave.commands.ShellCommand

[dokai]

The startTime variable in buildbot.slave.commands.ShellCommand? doesn't get initialized which results in an TypeError? in finished() when trying to calculate the elapsed time.

This happens on a vanilla 0.7.9 installation when trying run a test. Everything works fine on 0.7.8. The relevant traceback is below:

Here's another report:  http://article.gmane.org/gmane.comp.python.buildbot.devel/3633

The original reporter told me on IRC that this was actually a monkey-patch that they were running locally that was causing this problem. Don't know if it also applies to  http://article.gmane.org/gmane.comp.python.buildbot.devel/3633 , but since I reviewed the code and couldn't see how it could be wrong I'm closing this ticket.
