Summary:                    Ununitialized pointer in example rdfserialize.c
causes crash
Description: 
The example file  rdfserialize.c initializes a triple the following way:

triple=(raptor_statement*)malloc(sizeof(raptor_statement));

That way, it is possible for the triple->object_literal_datatype field to
contain an uninitialized pointer, which causes a crash on line 1431 of
raptor_serialize_rdfxmla.c when it tries to deference this pointer.

The best solution is to use calloc to initialize the triple:

triple=(raptor_statement*)calloc(1, sizeof(raptor_statement));
