[8.930][OPEN] RDP using HTML5 VPN Portal unable to connect

Hi,

just installed the update to 8.930, great work!

I'm now able to connect trhough the HTML5 VPN portal to a SSH session fine. However, when I try to launch a RDP session it fails. It gives the following error:

'An unknown error has occurred.'

The HTML5 VPN log shows:

2012:04:12-17:12:44 firewall screenmgr[4278]: Client 7: authenticated: user='franc'
2012:04:12-17:12:44 firewall screenmgr[4278]: Client 7: start screen requested: REF_CliConDc
