Re: NSTokenField bug in 10.5.2?

It appears the ML figured it out.

Yes, we did trim whitespace in 10.4, and the behavior change in 10.5 
caused binary compatibility problems with various applications.

We rolled out a solution for the binary compatibility problem in 10.5.2.
The logic to determine whether or not to apply the auto whitespace 
trimming is:
- trims if linked against 10.4.x binary
- trims if linked against 10.5.x binary and the delegate doesn't 
implement -tokenField:representedObjectForEditingString:
- does not trims if linked against 10.5.x binary and the delegate 
implements -tokenField:representedObjectForEditingString:
