Summary: steamcommunity.com certificate not recognised
           Product: Wine
           Version: 1.1.17
          Platform: Other
               URL: https://steamcommunity.com
        OS/Version: other
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: mshtml
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Trying to use the community tab in Steam gives an error dialog
"steamcommunity.com uses an invalid security certificate. The certificate is
not trusted because the issuer is unknown. (Error code:
sec_error_unknown_issuer)"

I think steamcommunity.com recently got a EV SSL certificate, so the problem is
probably that nssckbi.dll in wine_gecko needs to be updated.
