Bug#760191: akonadi-server: After upgrade 1.13.0-1 of akonadi-server, no new mail in IMAP folders is ever read

[Milko Krachounov <milko@3mhz.net>]

Package: akonadi-server
Version: 1.13.0-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

After upgrading two jessie machines to newest akonadi (1.13.0) and KDE, as well as libqt4-sql-mysql (4.8.6+git49-gbc62005+dfsg-1), any mails received since the upgrade (2014-08-29 and this morning, respectively) are not seen by kmail. There are no relevant errors in the akonadi error log (note to self: stop trying to use it, it is never going to get better), I cannot give any more details. I suspect the bug is triggered by libqt4-sql-mysql, because checking my last email timestamps would seem to correspond with it (it was pushed later than the other packages), but I have no way to tell for sure.

I have the following in a past akonadi server log, but it isn't present in any current one:
Control process died, committing suicide!

Also, akonadi control log contains the following on both machines, but it seems unrelated:
Executable "akonadi_nepomuk_feeder" for agent "akonadi_nepomuk_feeder" could not be found! 
Executable "akonadi_folderarchive_agent" for agent "akonadi_folderarchive_agent" could not be found! 

I manually ran mysql_upgrade on one of the machines, because MySQL was complaining about outdated tables. The other has not displayed any difference in logs. 

My mysql is version 5.5.37-1 (missing from the report below for some reason).
