Gnome-terminal crashes when opening a second one.

Ubuntu 6.04 Dapper Drake
gnome-terminal-2.13.0-ubuntu1

When a gnome-terminal is open and I open another one while the first one is still open, the second gnome-terminal fails to launch and the first one crashes.
This happens every time without fail.

This is the stack trace -
