 ### Fixed
 
-* [CRuby] `DocumentFragment#xpath` checks for error case introduced in libxml > 2.9.10. In v1.11.4 and v1.11.5, calling `DocumentFragment#path` results in a segfault.
+* [CRuby] `DocumentFragment#path` now does proper error-checking to handle behavior introduced in libxml > 2.9.10. In v1.11.4 and v1.11.5, calling `DocumentFragment#path` could result in a segfault.
