I recently got an alert from my HIDS (Host Intrusion Detection System) about this.
I then checked syslog for the entries around that time, here is an extract.
After reading the some more on this, I now know that this is a bug in Tracker, and there is a bug report here on it (this bug has been fixed in the Debian version), however as nothing is being done about that bug report at the moment, I need some sort of workaround. So I was wondering if there is any way to stop Tracker indexing file contents and so that it only indexes file names (although as disabling Tracker causes issues with other applications which depend on it, disabling it fully is not really an option)? As currently it is indexing file contents and then logging to syslog about it, so loads of stuff including my emails and other private data is going in there.
