dovecot - Sep 2010 - Panic: file mailbox-list-fs.c

Hi,

I have dovecot 2.0.3.
Mailboxes have been converted with dsync from mbox to maildir last week. 
There it was still version 2.0.2.

A user "produces" now this error:
  imap(userx): Panic: file mailbox-list-fs.c: line 150 
(fs_list_get_path): assertion failed:
  (mailbox_list_is_valid_pattern(_list, name))
Error: Raw backtrace: follows.

And all other imap processes are closing down. dovecot starts again.

master: Info: Dovecot v2.0.3 starting up

Additional
mail_location = 
maildir:~/maildir:INDEX=/addons/index/%u:CONTROL=~/control:LAYOUT=fs

namespace {
   inbox = yes
   list = yes
   location    prefix    separator = /
   subscriptions = yes
   type = private
}

Are there charachters which are not allowed or is there a reached a 
maximal length?


regards

There are lots of ways how the code could get here.

This could have been useful in pointing out where it's being called. A
gdb backtrace would be even better. http://dovecot.org/bugreport.html

There is some invalid character somewhere, maybe in a subscriptions
file. But it still shouldn't crash.
