Unfortunately that's what we did earlier and it was fine until gnome-terminal 
stopped accepting that option. Perhaps it's now a no-op in the version you're 
using, I'm not sure; but in 3.10 they made it trigger an error.

It ought not to be too hard to fix the hanging - hopefully someone with a GNOME 
desktop installed (not me) can figure out what's happening there.
