I have the same problem, in fact I have some apps that have 3 icons in Launch Pad (Address Book for example). All the the icons lanch the apps they represent. The multiple icons are all Apple apps except for a few exceptions. The two iCal icons show different dates!
Why do we have these multiple icons. How do we get rid of these multiple icons?
If I do use Launch Pad regularly (which is unlikely) I would like to chose the applications that are displayed in Launch Pad. Any ideas anyone?

I have 2 "Photo Booth" icons.
One is the latest version 4.0.
Another one is version 2.0.3 and I can't startup this.
"You cannot use the application Photo Booth.app with this version of Mac OS"
The same situation for iMovie, these version are '11(9.0.4) and '08(7.1.4).
I think this problems is caused by "Migration Assistance".
Because I migrated from MacBook to new iMac(model year 2010) in 2010.
iMovie '08 is installed only MacBook.

Try removing the Launch services plist files in preferences— there are several. May need restart after doing so, and see if it correctly rebuilds. In the Go menu ~/Library to get Library to show so you can see the preferences.
I believe it may be picking up previous versions/iterations of those apps held in the plist.

I believe I have found the solution to this problem on my computer. I used to create Alias's of all the applications I used regularly and kept a folder of these Alias's in the Dock so that I could quickly open them. It is these Alias's that are showing up as duplicate icons in Launchpad. When I trashed these Alias's the duplicates went away.
Hope this works for everyone! Good luck.

I hadn't done exactly this, but something like this. I had moved these applications to different folders within the applications folder when I was still running Snow Leopard. I guess when Lion updated these apps, it didn't find the originals so just wrote new ones. The old ones were still in their folders, so I just deleted them. Fixed the problem right away

Thank you, that solution worked for me. I too used to create aliases of applications to put in folders in the Dock, and as soon as I deleted them, the duplicates went away in the LaunchPad.

I found this really works for me
1. Run Terminal
2. Type sudo rm ~/Library/Application\ Support/Dock/*.db
to remove the problematic Launchpad database
3. Enter user password to permit change
4. Type sudo killall Dock
to recreate a new database
5. Exit Terminal
Once you completed the above all the docks will be closed, then you will be able to re-launch everything. The Launchpad will go back to the original setting (the app icons that you arranged previously will also go back to its original position - however this solve the duplication problem)
Good luck ~

That worked for me also ... I noticed that the only icons I had doubled were the iWork ones - and I did have iWork08 (in addition to 09). Trashed the 08 apps and that fixed my problem.
