Try archiving and unarchiving them. Its been working for the Angry Birds apparently. You will probably lose your progress though.....
I get that message as well, but find the app has installed anyway. No clue.
This: saying to uninstall some files from the library then try to reinstall.
What is the exact message?
The com.google.apps.gapps refers to the inbuilt Google Apps like GMail and Youtube and such.
If you're getting a message saying they crashed then it seems they aren't working or perhaps they didn't install properly. Can you get them to open up and work or not?
