Apparently, adding your Bootcamp partition to Privacy in Spotlight may correct the problem; it did for me.
Got that from an Apple support forum
System Preferences > Spotlight > Privacy then either click the '+' sign and add your Bootcamp partition, or, if your Bootcamp Partition is visible on your desktop, just drag it into the Privacy section.
iPhoto (iLife '11) wouldn't open on my MBP, running 10.6.6, starting yesterday afternoon. I updated to 10.6.6 weeks ago, don't know why this issue just started yesterday but this procedure corrected it.
