How to count visits for pageUrl that contain "a=1"

I have been trying to do it for two days but I get no results. I tried

http://localhost/aqar2/piwik/index.php?module=API&method=Actions.getPageUrls&idSite=1&segment=pageUrl=@a%3D1&period=day&date=last10&format=xml&token_auth=a688c5c011dac27cf125eaa84f95e59b

This is a bug that is fixed in 1.7 beta: 301 Moved Permanently
