"found no video or audio data in input" for everything -- Debian

[lessbones]

No, of course I realize it's not going to work without any forwarding-- generally I've been using Xpra and it's been working great... on the old binary.  I was just pointing out the differences between the two-- with the one from downloads I can get into the GUI with no problems using Xpra, or forwarding with "ssh -Y user@host" but with the new one it throws the xcb error, and it does so before ever trying to interact with the forwarding method.

I'll see if there's some way I can upgrade my Qt installation.
