Quicksilver doesn't work on my new Mac: all searches return nothing.
For example I try searching for Mail.app by invoking QS and typing
'mail'; no results are shown, and when I press the down key to reveal
all matches they're empty, even though the word 'MAIL' is shown above
the results tray, indicating my keystrokes were registered. This is
despite the fact that I've checked my catalogue via QS's preferences
and its populated as I'd expect it to be, with Mail.app showing under
the contents of 'Applications'.
