dovecot - Apr 2012 - 2.1.5 problem with mail_location

I've been advised to set :
mail_location = maildir:~/
as the home directory is found through a sql request.

this has been working perfectly up to and including 2.1.4

from 2.1.5 however this setting gives cause to a problem :
instead of looking in the mail home eg /var/mail/domain/user\@domain/ 
dovecot is looking for mail in /var/mail/domain/user\@domain/~

the '~' directory is created upon the first request for mail and all 
future mail transactions in dovecot is done relative to this folder.

is this behavior a bug or a feature ???

Yeah, it's a bug. Fixed and added to tests so it won't break in future:
