If the limit parameter is set to something other than the default of 50 on [[Special:Newpages]], and the 'newer x' or 'older x' link is clicked, only 50 results are shown, regardless of what the limit was.
I don't see this happening
I tested it some more, and it is a problem only when the limit is set to the same number as the "Number of edits to show in recent changes, page histories, and in logs, by default" preference.
Fixed in r40811.
