Tracker Applet

Tracker Applet.
"There was an error while performing indexing: Index corrupted."

Since I upgraded to Ubuntu jaunty (9.04) from 8.10, I am getting the above message frequently. Which will stay there, asking for an indexing, where it will never disappear even if we positively respond to its query. So regardless of our response, this message thingy will be popping up again and again.

I found a temporary solution for this well known bug from web.
sudo apt-get install tracker-utils
tracker-processes -r # --hard-reset

This bug was not appearing after that for a long time, but appeared again today!
Had to do tracker-processes -r # --hard-reset again.

The terminal output follows:

pradeeban@pradeeban:~/c$ tracker-processes -r # --hard-reset
