dovecot imapd process crashes using dovecot-solr

[Hasse Hagen Johansen]

I had my dovecot successfully configured for using solr for fulltext search with dovecot on my ubuntu 13.04. Now I have upgraded to 13.10 and I now see this in the log crashing the imapd process(and I don't quite understand why maxfd can less than zero. I Did try disable apparmor but it didn't help):

Sorry. I think this bug can be closed. It works now. I think it just needed to be reindexed

[Hasse Hagen Johansen (hasse-launchpad)]

Ok. I lookedsome more into this bug. The imap process is not coredumping anymore when accessing the mailbox via imap (for some reason I cannot quite understand)

But I cannot update the text index anymore. I have found what seems the exact same bug reported in debians bugtracker http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=719666

I have checked the versions of the debian bugreport against the versions installed on my Ubuntu system. They are the same for dovecot-solr and libvurl3.

I can also reproduce it on a newly installed Ubuntu 13.10 in a virtual machine. By installing dove-solr,solr and configuring it. Then sending a couple of mails to the user and then try to do a "/usr/bin/doveadm index -u <user> INBOX"

So it seems that dovecot fultext search with solr is broken :(

Sorry for my original confusing bugreport

Status changed to 'Confirmed' because the bug affects multiple users.

While cleaning up I did several solr tests recently (Yakkety) and it was working fine.
Thast said I can't sort out where in between it was fixed, but it should be valid to set the Ubuntu Devel release to Fix Released.
