Due of the the fact that I provide all the data for the pasteboard in the
same method where i call -(int)declareTypes:(NSArray *)newTypes
owner:(id)newOwner, now I've set newOwner to be nil.

Now, the icon is released (I can verify this with a NSLog() in dealloc).

But, the problem remains and the gdb trace is identical !
I'm seeing for myself that this is a pasteboard problem...

I've also changed in the sources all the little things that, perhaps,
could contribute at the problem, but these weren't many...

Please, get it; so we can discuss on the same basis.
