+Subject: [TagLibExtractor] Fix crash on invalid Speex files
+
+Summary:
+TagLib::Ogg::Speex::File::isValid() returns true even for invalid files,
+but tag() only returns a valid XiphComment when the file is valid.
+
+Other TagLib::Ogg::* classes properly clear the valid flag when
+encountering files.
+
+See https://github.com/taglib/taglib/issues/902
