deadlock

[James]

Hello,

Been using offlineimap for years and love it. Thanks to those that
have spent their time writing this awesome tool.

It seems that in the last day or so something has happened that has
resulted in offlineimap ceasing to function when checking email. After
the 5min configured window (autorefresh = 5), offlineimap will attempt
to sync with the mail server.

 *** Processing Account work
INFO:OfflineImap:*** Processing account work

Then nothing.

I have to force the process to stop (CTRL + \), and based on the
output it appears that the process is deadlocked. Several of the
threads and the Sync Runner stop at line 340 of the python threading
library, function waiter.acquire().

Unsure where to start troubleshooting this. This was working fine
until about 48hrs ago and haven't changed anything on my system.

Any thoughts appreciated.
