Still can’t get my Service to trigger.

The first two lines after the command always appear. The rest of the lines happen every time I open the Services menu, no matter the context. (The error messages are happening when the system checks if my Service qualifies.) Web-searching got only one hit on "is disqualified because its send and/or return types cannot be handled by the requestor”; the page was from Stack Overflow. It mentioned a post on this list from 5 years ago, suggesting adding an “NSRequiredContext” entry. It didn’t help me; still getting the same error. (The “MaxSize” numbers are one huge line; it wraps here.)
I’m stumped. I’ve been looking for Apple sample code, but since it likes tacking on “service” to 80% of its stuff, I can’t find anything.
Here’s the Services portion of my Info.plist, in case I’m still missing something simple:
> <key>NSServices</key>
> <array>
> <dict>
> <key>NSMenuItem</key>
> <dict>
> <key>default</key>
> <string>Open URL</string>
> </dict>
> <key>NSMessage</key>
> <string>openURL</string>
> <key>NSPortName</key>
> <string>Prairie</string>
> <key>NSSendFileTypes</key>
> <array>
> <string>public.text</string>
> </array>
> <key>NSRequiredContext</key>
> <dict>
> <key>NSServiceCategory</key>
> <string>public.text</string>
> </dict>
> </dict>
> </array>
I could post the source code again, but the lack of any logging from that method means the process is failing before the method would be called. I did at one time add an -init and -dealloc with logging just to make sure the object was created and retained. I got just the init message, which means that the service provider was being retained and not instant-deallocated.
Oh, the Stack Overflow page was <http://stackoverflow.com/questions/1370616/nsservices-not-working> and the referenced post was <http://lists.apple.com/archives/Cocoa-dev/2009/Sep/msg00201.html>.
