Thread:Project:Support desk/Search for term 'gz' in main page search box returns x-gzip encoded file

Not sure if this is the right place to post this bug...

From the main english Wikipedia page,

Enter 'gz' in the search box and press return or the arrow.

Instead of seeing search results, a file called "Gz.gz" is downloaded to the desktop.

The server responds with ContentEncoding set to gzip.

When uncompressed. the file Gz.gzip contains the HTML code for the disambiguation page.
