Thanks Aki! The fix works! Will give you the debug stuff of the other error next week.

Hi,
While testing our migration to dovecot 2.3.0, we encountered 2 panics, 1 segmentation fault while we wanted to rebuild the solr indizes. Problem [1] was encountered while rebuilding the indizes, and now I don't know how many mails/documents are indexed or where it got stuck. [2] and [3] encountered while just playing around, since I did not know of "tokenize" and did not find a lot of information about it.
This is a ubuntu 16.04 machine, dovecot 2.3.0 compiled from source ( + the patch for the recent zlib problem). "doveadm index" runs on a ~ 4GB mdbox-zipped-mailbox for about 3-4 minutes before aborting with the message above, beforehand I did a "/opt/dovecot/bin/doveadm fts rescan -A". When I repeat "doveadm index" it aborts after about 4 seconds, after a "/opt/dovecot/bin/doveadm fts rescan -A" it runs again for 3-4 minutes.
Apache tika logs, but those are probably not related to the problem, however, the devs might want investigate the last line: WARN Parse exception Expected ';', got "," determining content disposition javax.mail.internet.ParseException: Expected ';', got "," and org.apache.tika.exception.ZeroByteFileException: InputStream must have > 0 bytes
I would be happy if you could have a look at this, please, and of course just tell me what further information you need.
Thanks, infoomatic

You can fix this with https://github.com/dovecot/core/commit/5c1837529e6957da3e389683c43bd00685939...
[2] This was just about my curiosity since I haven't used "tokenize" and did not find too much info about it: /opt/dovecot/bin/doveadm fts tokenize -A '*' Panic: file doveadm-print.c: line 142: unreached Error: Raw backtrace: /opt/dovecot/lib/dovecot/libdovecot.so.0(+0xc5eea) [0x7f38ac5c2eea] -> /opt/dovecot/lib/dovecot/libdovecot.so.0(+0xc5f59) [0x7f38ac5c2f59] -> /opt/dovecot/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f38ac5355e1] -> /opt/dovecot/bin/doveadm(+0x3b3d3) [0x55c728e8b3d3] -> /opt/dovecot/bin/doveadm(+0x2a63a) [0x55c728e7a63a] -> /opt/dovecot/bin/doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x21d) [0x55c728e7b2cd] -> /opt/dovecot/bin/doveadm(doveadm_cmd_run_ver2+0x575) [0x55c728e8aeb5] -> /opt/dovecot/bin/doveadm(doveadm_cmd_try_run_ver2+0x37) [0x55c728e8af07] -> /opt/dovecot/bin/doveadm(main+0x1d2) [0x55c728e6a032] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7f38ac153830] -> /opt/dovecot/bin/doveadm(_start+0x29) [0x55c728e6a439] Aborted (core dumped)
This one sounds like a bug, we'll look into this.
[3] /opt/dovecot/bin/doveadm fts tokenize -u user1 "@" Segmentation fault (core dumped)
Can you run this in gdb with debug symbols and provide bt full?
