Symbol not found _OBJC_CLASS_ when launching app in 64 bit

My fat 32/64 Mac app is crashing at launch on 10.6 as follows:

Dyld Error Message:
 Symbol not found: _OBJC_CLASS_$_NSDataDetector
 Referenced from: /Applications/Mellel.app/Contents/MacOS/MyApp
 Expected in: /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation
in /Applications/MyApp.app/Contents/MacOS/MyApp

1. I’m aware that NSDataDetector is not available on 10.6 and I’m checking at run time to see if I can use it or if I need to use my home-grown stuff.
2. Up until recently the app was 32 bit only, and ran just fine on 10.6
3. I’ve just added 64 bit support so I suspected that the problem was related.

I’ve asked the users to force the app to run in 32 bit mode and the problem is indeed gone so I guess it’s safe to conclude the problem only happens when you run in 64-bit mode (and possibly only on 10.6)

What am I doing wrong here?

Thanks in Advance,
