I'm not sure if this is the same issue or if it should be reported on its own. But in my case, the miner was filling my / partition by filling the syslog with repeated logs.
The following message gets repeated endlessly: Jan 25 12:44:04 localhost tracker-miner-f[14902]: File 'file:///path/to/directory/in/Downloads' has been reenqueued more than 2 times. It will not be indexed. Jan 25 12:44:04 localhost tracker-miner-f[14902]: File 'file:///path/to/directory/in/Downloads/file' has been reenqueued more than 2 times. It will not be indexed.

I rerun tracker-preferences to make sure that indexing would not proceed if less than 20% of free space is available, but it seems that tracker-store ignores it. After I noticed that I had left only 44Kb free on the home partition, I deleted the cache from another program and I noticed that tracker-store filled up again the disk space that I freed few minutes before.
