[Mediawiki-api] Bug on querying revisions

[S. Nunes]

Hi,

It seems that there is a bug on the MediaWiki API regarding querying
old revisions.

The following call to the API should return the first revision made to
the "Tamilla_Abasova" article.

http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=ids&rvlimit=1&rvdir=newer&titles=Tamilla_Abasova

However, instead of returning 37099272 (the correct answer) the value
returned is 216581660 (the latest revision).
This problem seems to happen only when the article has a small number
of revisions.

Is this a known problem?
Where should I submit this bug report to?
