[Tracker] Tracker stuck

[Frimann Kjerulf <laukur gmail com>]

Hi there

I've been using tracker 0.14 for some time and it's been working great. I'm on a Ubuntu 12.04 server. Recently the tracker doesn't seem to be updating. 

The only thing I noticed is that APT was complaining about broken packages. Some problem with Mysql-server-5.5. I'm not using sql at the moment so I purged that. Shouldn't affect Netatalk, or would it?

When I run tracker-control I see that the tracker is stuck at “initializing” and Applications is stuck at 2%:

I tried killing the miners and running them manually with verbose mode set to debug by running "/usr/lib/tracker/tracker-miner-fs -v 3", showing that Applications miner seems to be stuck in a loop and showing this message again and again:

----------------------------------------------

         nie:url "file:///usr/share/applications" ;

         nfo:fileLastModified "2016-02-28T10:29:51Z" .

---------------------------------------------

I tried disable-ing the applications miner by running: " "/usr/lib/tracker/tracker-miner-fs -v 3 -d applications” and things started to kick off finaly! Here’s the tracker-control output:

---------------------------------------------

frimann baldur:~$ tracker-control

28 feb 2016, 11:08:56:  ✗     Emails                - Not running or is a disabled plugin

----------------------------------------

And I'm again able to search usingn the tracker-search tool. This is not really a good solution since I have to run the miners manualy. Any one know how I might go about fixing this permanently? 

Btw I'm using the tracker in combination with Netatalk 3.1.8 if that makes any difference.

Kær Kveðja / Kind Regards
