Persistent timeout uploading email to gmail inbox

[seanh]

Anyone know what the problem might be here, or what I might be able to
do about it? I'm getting this from offlineimap 6.5.4 every time I sync
my gmail inbox (this was offlineimap run with -d imap):

 ERROR: Exceptions occurred during the run!
