[poppler] Problem getting object identifier

[Leonard Rosenthol]

IIRC (I don't have the Xpdf/Poppler sources with me at the moment),  
you first need to check isIndirect() on the object.  If it's  
indirect, then you can coerce to an indirectObject or objectReference  
(forget the name) class which has objectID and objectGen members.
