Offlineimap crashing with "/." seperator

[Nathan Huesken <offlineimap@xxxxxxxxxxxxxxx>]

Hello,

Offline imap crashes on me with the error message giving below (it is very bad 
formated, but offline imap gives it me this way).
I believe this is due me using /. for the sep value in local Repository (it 
works with / for sep).
Is it somehow possible to use this seperator?
Thanks!
Nathan
