Comment 12 for bug 264306

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')
deliver(mathiaz): Apr 18 14:57:53 Error: Raw backtrace: /usr/lib/dovecot/deliver [0x7f06f76ebab2] -> /usr/lib/dovecot/deliver(default_fatal_handler+0x37) [0x7f06f76ebbc7] -> /usr/lib/dovecot/deliver [0x7f06f76eb1e8] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0x7f06f6cb0170] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0x7f06f6cba387] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_eval_bc+0x47d) [0x7f06f6cbb4ad] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(sieve_execute_bytecode+0xf6) [0x7f06f6cc1116] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so(cmu_sieve_run+0x318) [0x7f06f6cb1188] -> /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so [0x7f06f6caf0eb] -> /usr/lib/dovecot/deliver(main+0x1032) [0x7f06f76803a2] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7f06f6ee95a6] -> /usr/lib/dovecot/deliver [0x7f06f767dfb9]

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.
