error "'NoneType' object has no attribute 'group'" when connecting to Lotus Domino IMAP

[Riccardo Murri]

When connecting to a Lotus Domino IMAP server, the following Python traceback is printed:

Traceback:
  File "/usr/local/Cellar/offline-imap/6.5.4/libexec/offlineimap/accounts.py", line 234, in syncrunner
    self.sync()
  File "/usr/local/Cellar/offline-imap/6.5.4/libexec/offlineimap/accounts.py", line 290, in sync
    remoterepos.getfolders()
  File "/usr/local/Cellar/offline-imap/6.5.4/libexec/offlineimap/repository/IMAP.py", line 268, in getfolders
    imapobj = self.imapserver.acquireconnection()
  File "/usr/local/Cellar/offline-imap/6.5.4/libexec/offlineimap/imapserver.py", line 294, in acquireconnection
    imaputil.imapsplit(listres[0])[1:]
  File "/usr/local/Cellar/offline-imap/6.5.4/libexec/offlineimap/imaputil.py", line 148, in imapsplit
    retval.append(m.group('quote'))

The problem apparently stems from Lotus IMAP wanting to use '\' as a folder separator, and that is not catched by the regexp that offlineimap uses.

I've verified that it works on my Ubuntu 12.10 system.
