CocoaDiscussions - NSAppleScript Memory Leak

Lately I seem to be getting a memory leak whenever i use NSAppleScript.

The code is very simple and it is as follows; 

	[[[[NSAppleScript alloc] initWithSource:@"tell application \"iTunes\" to next track"] autorelease] executeAndReturnError:nil];

As you can see the applescript is autoreleased so this shouldn't be a problem, however whenever I run it, it leaks the following (And leaks again if ran again):

Anyone have any ideas?

AppleScript leaks no matter what you're doing. Even a simple compiled AppleScript Studio application will have around 3 leaks. This is a known problem with the current version and implementation of AppleScript. I'm not completely up-to-date on Apple's plans, but I do know they're working on fixing a number of such problems. So, it's nothing new. You can run "leaks" on any AppleScript Studio or ObjectiveC application with AppleScript and will likely find leaks in every single one.
