Quicksilver won’t install any plugins and hangs when trying
This is usually a permissions problem and kGTD has been known to
cause problems. Check that your user account (and not root) owns ~/
Library/Application Support/Quicksilver/ and the PlugIns folder
beneath it. You can check and change this if needed by doing Get Info
in the Finder and looking in the Ownership & Permission section.
After making sure the folder exists and you own it and have
permissions to write to it, restart Quicksilver.
The other cause is if you’re running Little Snitch which is a reverse
firewall and prevents Quicksilver from contacting the server where
the plug-ins are. TODO: I’m not sure if Little Snitch can be
configured to to allow Quicksilver to work or if you have to disable it.
