Comment(by lifeless85):

 ok, can you also explain why ?
 what about the other three query vals ? i see you stripped them from the
 tags, but to me looks like they suffer from same problem ...
 I see 2.9.2 has been released ... sorry for setting that milestone... now
 that we need a patch, how can i help ? i can write it ? i should post it
 here or i should use some kind of svn ?
