Yes.  Here's what I reported (on the "streaming" mailing list, not 
this one) last month:

>I have just tried testing "RTSP-over-HTTP" streaming using VLC 1.1.5 
>(as a client), and can confirm that the "Tunnel RTSP and RTP over 
>HTTP" option (in Preferences -> Input & Codecs -> All (button) -> 
>Demuxers -> RTP/RTSP) is broken, at least in version 1.1.5.
