gnome-terminal crashed with SIGSEGV in g_type_check_instance_cast()

[Dan N.]

Steps to reproduce:
1) (login with xubuntu session)
2) (install gnome-terminal)
3) start gnome-terminal
4) create new tab in running gnome-terminal (Shift+Ctrl+T)
5) detach this new tab
6) run vi, vim or mc in this detached tab

Expected: start application vi, vim or mc without problem
But: crash all running gnome terminal

---------------------------------
Without detaching tab is no problem.
