Problem to access folder that start lowercase s

[leire]

I've a problem to access folder that start with 's' (but not if 'S' and other folders with lowercase letters).
In my usually imap client (thunderbird), i haven't problems with these folders.

Message error:
Server Error Status: Mailbox does not exit, or must be subscribed to.

Hi.
I had the same problem after portupgrade on my FBSD platform.
Solution is rename "by hand" per e-mail account folder .sent to .Sent and in web GUI change sent folder in roundcube options.

I just upgraded to 0.5-stable version and this problem is not found.
I can use folders with s :-)
