A project that shows the leak

The method NSData.ToString leaks.

The attachment includes a project that show the leak and a file of XCode Instruments "Memory.trace" that shows an execution of the project. The project has 3 buttons. The first one shows the memory leak. The second proves that is NSData.ToString that generates the leak. The last button proposes a work around I will use for now.

Looks like a refcount issue in manual bindings. Looking into it...

Confirmed, there's an extra retain on the native NSString.
