ParseException for most, but not all queries

[graue70]

Most, but not all queries on wikidata-full yield an exception similar to this one:
Exception: ParseException, cause: Expected a token of type IRI but got a token of type SYMBOL ()) in the input at pos 527 : ) . FILTER langMatches(lang(?description), "en") } ORDER BY DESC(?sitelinks)

This affects many of the example queries, including two of the first three.

This is due to a small bug introduced by one of the (not so) recent changes.

Please use FILTER (lang(?description) = "en") instead of FILTER langMatches(lang(?description), "en"), it's better anyway

PREFIX wd: 
PREFIX wdt: 
PREFIX schema: 
SELECT ?name ?population WHERE {
  ?city wdt:P31 wd:Q515 .
  ?city wdt:P17 wd:Q183 .
  ?city wdt:P1082 ?population .
  ?city schema:name ?name .
  FILTER (lang(?name) = "de"))
}
ORDER BY DESC(?population)

Exception: ParseException, cause: Expected a token of type IRI but got a token of type SYMBOL ()) in the input at pos 306 : ) } ORDER BY DESC(?population)

Eine Klammer zu viel :-)

FILTER (lang(?name) = "de")) -> FILTER (lang(?name) = "de")

Oops :) Thanks.

The examples should be updated, however.
