Sorry about noise. Just realised CFPreferences doesn't like
NSURL/CFURL.

Your code sample cuts off before (I think) it gets to the last point of contact 
with your code in the crash. We don't see any use of the keys and values 
arrays. Could you offer a complete listing, and tell us where in the method the 
crash occurs? Give us the full stack trace, which might provide a clue of what 
went wrong.

Also, have you verified the types of url, displayName, and browser? If your 
url is an NSURL/CFURLRef, that's likely your problem; the ternary operator 
shows you expect the value to be a CFString.

Sorry about cutoff. Don't know what happened. Let's try again (is
there a maximum message size?). 

Hello. This piece of code causes
CFPreferencesSetAppValue() to crash: 

- (CFDictionaryRef)
createBlockSaveData { 

CFDictionaryRef parent=[super
createBlockSaveData]; 

CFStringRef keys[]={CFSTR(LinkBlockURL),
CFSTR(LinkBlockDisplayName), CFSTR(LinkBlockBrowser),
CFSTR(BlockType), nil}; 

CFTypeRef values[]={url ? (__bridge
CFTypeRef)(url) : CFSTR(null), 

displayName ? (__bridge
CFTypeRef)(displayName) : CFSTR(null), 

browser ? (__bridge
CFTypeRef)(browser) : CFSTR(null), 

CFSTR(LKBLockTypeURL), 

nil};


CFMutableDictionaryRef d=CFDictionaryCreateMutableCopy(nil, 0,
parent);
