Hi,
Those two calls are really just redundant. 
Objects are already mapped directly in the marshaller, so they don't need to 
use mapObject.

to achieve the same, just change:

-        if( sc.hasVirtual() )
               mapPointer(obj, &o, pointer_map, o.classId, 0);

in handlers.cpp but this is wasteful. 

This should rather be fixed in kalyptus. We should set cf_virtual the minute a 
class has a virtual method regardless of the dtor, even if mapping cleanup is 
then problematic as Richard pointed out.

That beeing said, I don't think it is much of a problem for PerlQt, as the 
object table has weak references, so pointers are deleted when the Perl 
object is deleted.
