Nice... For me simply removing the "version" part fixed the problem. A simple 
"try and ask forgiveness" patch wasn't as simple as I thought, the actual 
terminal command execution is being done elsewhere.

On newer Ubuntus, the "--version" just hangs, probably waiting for terminal 
input or something silly like that.

For now, I'd say removing the version check would be better - if you happen to 
have that bad 3.10 version, you get a nice error message. That's a lot easier 
to diagnose than a hangup.

To be quite honest, I don't know what desktop I'm running. I just run whatever 
was default with Ubuntu, so that might be Gnome...
