I somehow missed this before. You are taking the xml from the passed
custom_conf in gvir_domain_save_to_file_async but you are not passing
it to gvir_domain_save_to_file here but rather getting the existing
config from the domain. You want to keep a ref to the original custom
config object (no need to get xml string out of it) and pass it here
through the DomainSaveToFileData. g_strdup/g_free will have to be
replaced by g_object_ref/unref too.
