Matt, I've tried to process the three mbox files you've attached to this
bug. Both the 1st and 3rd one don't produce any errors.
However the 2nd one produces the following error:
deliver(mathiaz): Apr 18 14:57:53 Panic: file sieve-cmu.c: line 90
(unfold_header): assertion failed: (str[i] == ' ' || str[i] == '\t')

The reason the bug was closed the second time is that a changelog
mentioned this bug number again after this bug was reopened:
* Dropped:
- debian/patches/fix-message-parser.dpatch: Parsing an invalid message
address like "From: (" caused an assert-crash. (LP: #290901).
(CVE-2008-4907 - fixed in 1.1.6)
- debian/patches/login-max-process-count-warning.dpatch: Tell the user
that they have reached the maximum number of processes count.
(LP: #189616) - Different implementation from upstream.
- debian/patches/fix-dovecot-sieve.dpatch: Fixes assertion error
when a header string ends with a LF (LP: #264306). Implemented upstream.
So it seems that the upstream patch provided for the first issue isn't
enough.
