This error appears also if a soap XML response contains special Unicode characters. In my case it was REPLACEMENT CHARACTER (U+FFFD).

In details, inner function of the SoapClient xmlParseDocument sets xmlParserCtxtPtr->wellFormed property as false after parsing. It throws soap fault with looks like we got no XML document.
