[Mediawiki-api] Internal error in ApiResult::setElement

Hi, Something changed in the last couple of days that causes a bunch of API calls to fail when grabbing image dimensions. This error is consistently generated from the URL below: {"servedby":"mw72","error":{"code":"internal_api_error_MWException","info":"Exception Caught: Internal error in ApiResult::setElement: Attempting to add element imagerepository=shared, existing value is shared","*":""}} http://en.wikipedia.org/w/api.php?titles=File:Convento_Cristo_Decemebr_2008… Requesting the data separately, i.e. http://en.wikipedia.org/w/api.php?titles=File:Convento_Cristo_Decemebr_2008… and http://en.wikipedia.org/w/api.php?titles=File:Convento_Cristo_Decemebr_2008… give the correct result. Other multi-queries like http://en.wikipedia.org/w/api.php?titles=File:Convento_Cristo_Decemebr_2008… also consistently work fine. What's going on here? Thanks, Eric
