offllineimap is breaking

[Jagadeesh N. Malakannavar]

Hello,

I have been using offlineimap for sometime  with mutt. I was happy.
recently I upgraded my OS and now I am getting this error. I tried to
search in google for the solution but I did not get any. Will please help
me fixing it? This is quite urgent for me :-)
