Having a really hard time keeping Offlineimap running

[John Wiegley]

I haven't yet been able to get Offlineimap stable enough so that it keeps
running through a full day.  I'm even starting it with launchctl, so that if
it dies, OS X will simply start a new one.  But it doesn't just die -- it
stops working, so launchctl can't help.

Here's what I see in the logs from last night, about an hour after I went to
bed:

--8<---------------cut here---------------start------------->8---
Exception in thread Thread-622:

    raise typ(exc_fmt % str(val))

Is there any way to make Offlineimap more resilient to failure, so it simply
starts over if something goes bad?  After the trace above, the process became
non-functional and I had to kill it before Offlineimap would do anything
again.

My config file is below.

Thanks,
  John
