Trying to export any page from the MediaWiki namespace with Special:Export fails to give the page contents if the user doesn't have sysop rights on that wiki. Only the <siteinfo> section is output, the <page> section is missing.
Fixed in r30160.
SpecialExport.php was using $title->userCan('read'), which is alas *not* the same as $title->userCanRead(). It seems to return a result as if you wanted to edit or something...
This is horribly wrong and the permissions code should be fixed; for now I've replaced the guilty call with the userCanRead() which appears to return the correct result (same as the main wiki can-read check).
