Hangs on a specific message

I think it's an old bug, or at least this happens sometimes since 6.3.1

If I rerun it may sync some other emails, but when it gets to this
message 6301 it fails again.

The setup is the following: remote=gmail, local=imap (really gmail,
see my message above about not being able to use gmail as local).
Remote readonly=1. Trying to copy all mail from one gmail account
("remote") to another empty one ("local"). It worked fine with another
account, copied about 8GB of data.
