Error loading Ubuntu

Hi installed 2 weeks before and it was working fine.
I installed some extra plugin todays when it restarted, it started giving errors.

I tried solving it for an hour but no luck.

Finally what I did is... delete .Aptana folder from home directory and again run the Aptana.

Voila!!! It worked this time.

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!!!
