[8.930][ANSWERED] HTML5 VPN only works when Flash is installed

When using HTML5 VPN from a secured windows system with no browser Plugins and try to launch a session (no matter if the session is RDP or SSH), I get the message "Flash >=10.0.0 is required" and the session does not start.

I know from the partner roadshow that HTML5 portal was especially designed to NOT need FLash, Java, ActiveX or similar insecure plug-ins, so I assume this is a bug.
