Problems uploading and deleting files

From semantic-mediawiki.org

Ok, problem was definitively coming from:

http://www.mediawiki.org/wiki/Extension:RDFIO

which was calling that function. Going to try to solve it by making a clean instalation of it again (to see if i made an error, even if i know pretty much for sure that it sometimes randomly fails, from previous local instalations) and if that does not the thing, i will go for the complete stack trace.

Many thanks.

The `Exporter` should always be called using `Exporter::getInstance()->...`.
