I'd guess the problem is with Beagle thinking you should have Pidgin installed. If you don't use Beagle I'd uninstall that too.
Yes I would agree.
Beagle and Tracker are both still problematic and only useful for the subset of users who cannot properly organise their data IMO
I have had trouble with both in the past to the extent I wish all distros would default to not installing/enabling this indexing and/or pop up a prompt on first run saying "Are you the sort of person that loses stuff y/n"
Both have randomly brought my system to it's knees even when they are supposed to be low priority and only index when the system is idle and both have managed to corrupt their own databases and then generate continual popups saying the database is broken, whilst offering no option or suggestion to correct this.
To be fair the situation on Windows is no better :)
