I've deleted TextMate and its alias from Launchpad and Library - still have a "ghost" icon showing in all windows (see screenshot).
When I enter Launchpad that ghost icon (in last screen) won't delete even when the option key is held down and icon quivers.
If I scroll to first Launchpad screen the ghost icon automatically appears as the last item in that window, then auto-scrolls to next screen where ghost icon moves to last item again, etc. until it shows in the last Launchpad window by itself.
I've used AVG Cleaner with no change, ran the reindex option for Finder with no change.
Essentially, I can't use Launchpad since it auto-scrolls from any screen to the last screen with the ghost icon of "TextMate alias".
