[Mediawiki-api] Mediawiki Wikipedia API bug

[Robert Chin]

There appears to be some sort of bug affecting a subset of pages that
started happening yesterday night. Certain <img src=> tags on
Wikipedia's API are being served with an invalid URL, missing the
scheme in front:

<img src="//bits.wikimedia.org/skins-1.17/common/images/magnify-clip.png">

This is seen on http://en.wikipedia.org/w/api.php?action=parse&page=Cereal

However certain other pages, such as
http://en.wikipedia.org/w/api.php?action=parse&page=Actinide appear to
be fine.

Please let me know if this e-mail should go to some Wikipedia list instead.

Thanks,

Robert
