Try to delete the LS cache (requires admin privileges):
    /Library/Caches/com.apple.LaunchServices.*

90% of the time this seems to be what Finder uses to locate a program 
(and it does in my experience easily get “corrupted” if the same 
application shows up at different places or with different names).

After deleting it you should restart you machine, then navigate to the 
folder containing TextMate and start it (using the Finder).

There is also the following file:
    ~/Library/Preferences/com.apple.LaunchServices.plist

This contain file type -> application mapping, I do occasionally delete 
mine when I think something is wrong (also best to restart after doing 
this).
