Title: disable the paste action for multiple items. Fixes #593

The best solution would be to implement the new NSPasteboard methods introduced in 10.6, as you can pass an array of items to the pasteboard, and it will paste them all. This is a lot harder than it looks

This is an interim fix to avoid the crash.
