Since Apple's documentation 
<http://developer.apple.com/techpubs/macosx/Cocoa/Reference/ApplicationKit/ObjC_classic/Classes/NSWorkspace.html#BCIEEFBI>
 
says so we can asume you found a bug here. When I was working on the 
GWorkspace port to Cocoa (long time ago) I could never open a folder by 
doubleclicking it but only by using the open as folder command. After 
peeking at the sources I also suspected a bug in Cocoa but got never that 
close to it as you did.

I advise you to file a bug report with Apple 
<https://bugreport.apple.com/cgi-bin/WebObjects/RadarWeb.woa>. Since you 
already got the developer tools I think you are already registered as a 
developer with Apple (you need this to login the bugreporter), otherwise 
you can do it here <https://connect.apple.com/>, it will cost you nothing 
(free online membership).
