Quicksilver

I don't use Quicksilver but I'm sure you know that its development has been stopped a while ago so it's hardly surprising that it misbehaves in snow leopard.
you might want to consider some alternatives. personally, I use Butler and find it pretty wonderful. I don't see any issues with it in snow leopard so far and it's being actively developed (and is for now free).

hmm, I may be wrong about Qucksilver not being developed any more. I was basing my statement on posts by other posters on the forum. but based on your post and http://blacktree.com/ this appears to be wrong. then what you are seeing might be some temporary glitches which should be worked out eventually. and in this case it might not be worth while switching and getting used to a new system. i don't know how similar Butler is to Quicksilver as i only use Butler. it's a very nice application launcher. check out the link I gave you for more details.

sorry, as i said, I don't use Quicksilver. perhaps someone else who does will care to comment.

Another option is Lauchbar.

I've been switching between LB and QS off and on. I've been using LB more recently, and I haven't had any problems with LB and SL.

I found that removing these two plug-ins allowed Quicksilver β56a7 to run under Snow Leopard.
Find the Quickliver PlugIns folder which s/b in /Library/Application Support/Quicksilver (but was actually in my Users/myname/Library/Application Support/Quicksilver for my machine)
and remove these two plugins:

AirPort Module.qsplugin
Services Menu Module.qsplugin

QS was up and running again. Services has changed considerably and the plugin needs major rewrite. BTW - Go to System Preferences Services and turn ON "Send To Quicksilver" option while you are at it.

Open System Preferences, then click on Services (under System Prefs in the menu bar). Select 'Services Preferences', and you will see the option to Send to Quicksilver.

By the way, thank you Bob the Tomato.

Found this on the Snow Leopard Wiki. I see at least some of this was covered earlier:

b56a7 reported to work perfectly, though the "Services Menu Module" Plugin causes Quicksilver to crash on launch. You can delete/move "Services Menu Module.qsplugin" from "~/Library/Application Support/Quicksilver/PlugIns" to temporarily fix the issue. Other plugins may cause a similar crash, including the "Airport Module" plug-in. If you use Spaces and "Show Icon in Dock" is unchecked in preferences, when you invoke Quicksilver, it will only open in the Space that it was started in. Workaround is to have "Show Icon in Dock" checked, which is a bit annoying either way. Airport module crashes/doesn't work.

I've deleted all the preferences and plugins from Quicksilver in my user profile library and still cannot get this to run.

I'm appealing to the smart guys on this post.

Is there someplace else these could be hiding out? There is nothing in the top tier Library.

Just FYI - The console crash reports all seem to lead with this
Exception Type: EXC BADACCESS (SIGBUS)
Exception Codes: KERN PROTECTIONFAILURE at 0x0000000000000020
Crashed Thread: 0 Dispatch queue: com.apple.main-thread

I'm replying to my own post. Got it running (perhaps still finicky).

I think part of the persistent problem was a bum download of the application or some glitched up decompression.

Find the discussion below fairly interesting. It is now Nov 09 - and I still haven't been able to get Quicksilver working properly on SL. For instance, I have followed the advice below (deleting plug ins etc in my libary) - QS doesn't crash on opening - however, it doesn't find any of my document app searches either.

Any help fixing this would be appreciated. Thx
