Hi, All,

I found some "upload" changes missed page id:

http://commons.wikimedia.org/w/api.php?action=query&format=xml&continue=&list=recentchanges&rclimit=500&rcnamespace=0%7C2%7C4%7C6%7C10%7C14%7C100%7C828&rcprop=comment%7Cflags%7Cids%7Cloginfo%7Csizes%7Ctimestamp%7Ctitle%7Cuser&rcstart=2014-03-26T22:52:16Z

<rc type="log" ns="6" title="File:Doņa Luz Saviņon de Saviņon - Personalidsades de Las Calles de la Colonia del Valle en Mexico D.F..JPG"pageid="0" revid="0" old_revid="0" rcid="121543911" user="Mrtabachnik" oldlen="0" newlen="0" timestamp="2014-03-26T22:52:15Z" comment="User created page with UploadWizard" logid="83703391" logtype="upload" logaction="overwrite" img_sha1="9f5cptv556268ehsgio0akc3ld0ftau"img_timestamp="2014-03-26T22:52:14Z"/>

The page id was 0. I'm wondering whether it's a bug?

Thanks.
