Re: Leopard on PPC

It seems to be debuggable by yourself. Can you start up in XCode on 
PPC? If not you can simply launch the app under gdb and put a 
breakpoint at +[NSDictionary dictionaryWithObjectsAndKeys:] with br. 
From then it would be interesting to check the passed argument (on 
PPC the argument of a method function are in register $r3, $r4, be 
careful that an objective-C call will have implicit $r3 being self and 
$r4 being the selector). You can also also crash and simply go up in 
the backtrace. Then you can find which arguments is bogus (and then why)
