When issuing a query using a URL property, if the URL contains = signs SMW handles it wrong.

{{#ask: [[Has URL::http://www.wired.com/geekdad/2012/03/67-books-for-kids/?pid=1185&viewall=true]] | format=count }}

Generates an error:

Some subquery has no valid condition.

The equal signs are causing this. This query works fine and returns 0.

{{#ask: [[Has URL::http://www.wired.com/geekdad/2012/03/67-books-for-kids/?pid_1185&viewall_true]] | format=count }}
