Why does this Australian address always raise a 500 error?

This South Wales address always raises a 500 error. Anyone has an idea why this is or if its a bug that needs fixing?

The SQL for the query was too slow, so it timed out consistently on some of the servers. I’ve pushed a temporary fix.

See here.

For me, right now, it works.
Maybe there was a bug and it is fixed.

Weird! For me it still gives a 500.

Same Problem “500 Internal Server Error” from Munich, Germany for the original query.

Is OK as well, omitting the “+AU” in the query
