Once again, thank you very much for your help! It works now with 
the new @selector style, and I would had the biggest problems 
finding out that it was the destructor making dmd bail out a -11.

I just report another finding here. It's about properties and 
NSStrings. So far, it was possible to set the strings of an alert 
like this (source copied from the Chocolat example):

auto alert = new NSAlert ;
alert.messageText = "Want Chocolate?" ;
alert.informativeText = "Chocolate is sweet." ;

This now needs to be written like this:

auto alert = new NSAlert ;
alert.setMessageText("Want Chocolate?") ;
alert.setInformativeText("Chocolate is sweet.") ;

In the NSAlert class, the respective code is:

extern (Objective-C)
class NSAlert : NSObject {
   @property {
     NSString messageText() ;
     void setMessageText(NSString text) 
@selector("setMessageText:")  ;
		
    NSString informativeText() ;
    void setInformativeText(NSString text) 
@selector("setInformativeText:")  ;
   }
}

Of course, the property read/write access style is again just a 
convenience, but for somebody coming from Objective-C, it is 
"natural" to do it either way.
