Comment 3 for bug 914889

This problem exists in 12.04 "Precise" as well. And no matter how much you kill it, it keeps coming back. The process shows init as its parent:
rifter 5626 1 14 15:05 ? 00:00:48 yelp ghelp:///usr/share/gnome/help/gnome-terminal/C/gnome-terminal.xml

The only way to stop it seems to be to kill the terminal, for some reason. highly frustrating.

I'm using the 64 bit AMD version of Precise, btw.
