6.3.4-rc4 crashes

[Chris Dennis]

Hello offlineimap people

Offlineimap, as cloned from github less than 24 hours ago, is crashing 
for one user, with output as follows.

The context of the error in the code is:
454
455             (typ,dat) = imapobj.append(self.getfullname(),
456 
imaputil.flagsmaildir2imap(flags),
457                                        date, content)
458             assert(typ == 'OK')

Is this a known problem?

cheers

Chris
