Problems in starting Imap Daemon

[Sebastian Fohler]

If I want to start the imapd Daemon it begins to start the daemon and 
stop's after few seconds with the error message:

Feb 23 13:50:27 voyager service-imapd[11492]: executed
Feb 23 13:50:27 voyager service-imapd[11492]: unable to set close on 
exec: Bad file descriptor

Does someone knows where I can fix this problem, I've not much 
experience with the installation of the cyrus Imap Server and don't know 
where I should search the problem!
