Xpra: Ticket #1636: socket activation prevents ssl wrapping

First problem is that despite having --ssl-cert=/etc/xpra/ssl-cert.pem the proxy command line doesn't specify ssl=on.

More importantly, after enabling ssl (and workaround Ubuntu platform bugs: ticket:1521#comment:12), we still get an error:

(this error was only visible after fixing a typo in the error handler: r16806)
