Default Need help: Quick search crash!

Hi all,
I've rooted my Optimus One, JIT enable and overclock up to 768MHz... everything goes weel and I'm very happy but when I'm trying to search something using the quick search (search hardware button from home screen!)... it crash!
Probably I found the problem: if I select in the search criteria tha "Application" checkbox it crash, if I don't check the application it works.
I use root explorer to delete some standard apps I don't use... can be that the problem?
Any idea?

Is it possible to uninstall and install again the quick search, repair or reinstall it?


Many thanks!
