The guest-get-fsinfo command collects also information about PCI
controller where the disk is attached. When this fails for some reasons
it tries to return just the partial information. However in certain
cases the pointer to the structure was not initialized and was set to
NULL. This breaks the serializer and lead to crasehs of the guest agent.
