offlineimap stops working on 6.3.3 -> 6.4.2 upgrade

[Sean Whitton]

Hello,

I just upgraded offlineimap from 6.3.3 to 6.4.2.  On an attempt to sync I
am now getting this error:

,----
|  ERROR: Syncing folder drafts [acc: Nucifera]
|   unsupported operand type(s) for -: 'list' and 'set'
|  ERROR: ERROR in syncfolder for Nucifera folder drafts: Traceback (most
recent call last):
|   File "/usr/lib/python2.7/site-packages/offlineimap/accounts.py", line
406, in syncfolder
|     remotefolder.syncmessagesto(localfolder, statusfolder)
|   File "/usr/lib/python2.7/site-packages/offlineimap/folder/Base.py",
line 452, in syncmessagesto
|     action(dstfolder, statusfolder)

line 394, in syncmessagesto_flags
|     addflags = selfflags - statusflags
| TypeError: unsupported operand type(s) for -: 'list' and 'set'

I see this lots of time and then hit C-c.

This is my config file:

| pythonfile = .offlineimap.py

This is my python file:

My guess is that my python file needs changing somehow to support the new
version?

Any help appreciated.

Thanks.
