Hi all. When I try to fetch my file from Gmail with offlineimap, will get following errors:

------------------------------

I have tried delete some of my mails. And it can continue now. But it will appear soon. So I think there must be some mails blocking offlineimap in my Gmail. I have searched google, I'm not the only one who meet this issue.

Additional info:
* package version(s)
madper@madper ~ % offlineimap --version
6.5.4
* config and/or log files etc.


Steps to reproduce:
I'm not sure if you can reproduce it. it seems need some magic mails in your mailbox. (with some special encoding? or some magic attach?)
