I am trying to set up courier-imap and courier-imap-ssl (4.1.1-3) in
Etch, but I constantly run into vthe below when starting courier-imap

haven:/var/mail/Eriks Maskiner/erik/new# /etc/init.d/courier-imap start
Starting Courier IMAP server:/etc/init.d/courier-imap: xrealloc:
../bash/subst.c:512: cannot reallocate 512 bytes (0 bytes allocated)

Any hints?
