iPhoto duplicate in launchpad

Hi there,

I have a problem with iPhoto duplicate in my Lunchpad.

I have read most of the threads here (I believe) regarding application duplicates in Launchpad, but I can't seem to find a solution.

Most people appear to have problems after osx lion upgrade from snow leopard.

I, on the other had, have just bought the new Macbook Air with OSX lion native on the system.

I have gone through the usual post unboxing update, and updated iPhoto through the app store. Since I have done this, I have 2 iphotos in my launchpad, both of which launch the same version number of iphoto. (9.1.5):

• i have done a spotlight search of "iphoto", this only turns up one application in the folder
• there is no duplicate application folder anyway as this was not an upgrade from an older osx
• there is no duplicate of an older version of iphoto in the application folder
• i have even gone so far as deleting the dock iphoto icon
• i have even deleted my whole iphoto library (they're backed up elsewhere)

In short I have no idea where the duplicate is...

Any one have ideas?
