The IMAP resource.

The first character of the IMAP RID is the path separator (which is variable 
in IMAP, seems to be '.' on your server). Take a look at the code that 
determines the RID for a newly created folder, I bet it takes the separator 
from the RID of its parent collection. And for top-level folders you end up 
with 'i', because the RID of the IMAP root node is an URL "imap://...".

I think this is the IMAP collection syncing trying to create your newly 
created folder locally, causing a name clash. It's not recognizing the already 
existing local one due to the broken RID.
