It currently shows this page if it cant parse the user agent. Can you post the url with the error? It would help us debug.
This is an error page and I am requesting the page using Chrome (18.0.1025123) on Android ICS (4.0.4 on a Galaxy Nexus).
Something to note - if i check the "request desktop site" setting in chrome it seems to work, but that may be because chrome pretends to be running on linux in that case.
