Folder %blah. does not exist, create it? (y or n)

Hello list,

my .folders file has only one entry: "%/". Every time I start Wanderlust (M-x
wl) it starts syncing all folders iteratively, until it reaches the "blah."
folder. Then it stops, and asks me the question in the subject:

Folder %blah. does not exist, create it? (y or n)

No matter what I answer, it never proceeds with syncing the rest of my
folders. If I answer "n" then it just stops. If I answer "y" then I get the
IMAP error that the folder already exists.

The "blah" folder on my IMAP server is a folder with many subfolders. But
there is no "blah." that Wanderlust sees (notice the trailing dot). In fact,
dot is the path separator so it is a forbidden character for a folder name!

Any ideas on how to debug this further and see why Wanderlust sees the
trailing dot in the folder name?


Thanks in advance,
Dimitris
