GSA reports HTTP 500 error when testing with the sample html page.

Any idea what could cause this problem? It is true that I loaded the HTML from disc with Chrome on OS X.

Maybe I need to host it to a web server? Or maybe it is something wrong with our GSA instance? -- It works well with normal searches.

+1 also seeing this error after uploading the XSLT to the GSA. Our searches work perfectly otherwise.
