Lets just say I hate Nokia N9's OTA upgrade. I've had it when it was updated from Pr1.1 to 1.2. And now it's the old nightmare all over again.

After the upgrade, I saw broken images in the gallery and never-ending updating of the music library.

Typed in "top" in the Terminal and that evil tracker process ate 100% CPU and just wouldnt give up. And of course, after about 3 minutes, I had in my hand a really hot stick.

So apart from reset the device, here is what we can do and it works like a breeze:

Reboot the phone and let tracker do a clean index. You will not lose any images or music files. But do a backup of contacts first, just in case. If you are using an MfE account to manage your contacts, disable the account first and then enable it back and do a full sync.
