There was an error while performing index

This error is seen often in Ubuntu 9.04. It pops up a dialog box which says "There was an error while performing index". It has 3 buttons, Re-Index, Cancel and one more (I forgot ;) ). No matter which button you click, it again pops up the same dialog box. Really very annoying :( .

I googled for it and found simple solution to it.

Delete the following files and reboot your system
1. ~/.local/share/tracker/data/ ( rm -rf ~/.local/share/tracker/data/ )
2. ~/.cache/tracker ( rm -rf ~/.cache/tracker )

That's it!!!
