Exactly right. It contains the line "owner lrwstipke".

I just now reproduced the crash again. None of the Maildir folders 
contain anything pertaining to ACLs (no dovecot-acl or dovecot-acl-list 
files) and the Sent folder is the only one with an ACL set. The log file 
again shows

Panic: file acl-backend-vfile.c: line 1124 
(acl_backend_vfile_object_update): assertion failed: (!update-
>rights.global)

Anything else I can provide?
