Working 6.3.4 config breaks in 6.5.2.1

[Michael Williams]

Hi,

my working 6.3.4 configuration fails in 6.5.2.1. Here's the config (with the fully-qualified server name replaced with [SNIP]).

[general]
accounts = mpe
ui = blinkenlights
pythonfile = ~/usr/bin/get_pw.py

[Account mpe]
localrepository = localmpe
remoterepository = remotempe
presynchook = imapfilter
postsynchook = notmuch new

[Repository localmpe]
type = Maildir
localfolders = ~/.mail/mpe

[Repository remotempe]
type = IMAP
remotehost = imaps.[SNIP]
remoteuser = williams
ssl = yes
nametrans = lambda foldername: re.sub('^INBOX.', '', foldername)
maxconnections = 5
remotepasseval = get_pw("imaps.[SNIP]")

Here's this working with 6.3.4 (I manually aborted it to truncate the output, but it does complete).

And here it is failing with 6.5.2.1.

Any suggestions?
