Another brick in the (corporate) wall

When trying to open GMail, Google Reader or other Google sites that require authentication, I got the following error:


              Error 107 (net::ERR_SSL_PROTOCOL_ERROR): Unknown error.


I am behind a proxy, that authenticates itself with certificate to GMail. So the traffic goes encrypted to the proxy and only then the proxy encrypts it with the certificate from Google. Anyway, to pass this I added  the --use-system-ssl option for the Chrome shortcut, in the Target field, like: 


"C:\Documents and Settings\\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" --use-system-ssl


I found too little information on the issue and also on what this parameter does, so any information is welcomed.
