I don't use gnome terminal, but for lack of anyone throwing anything else against the wall, the next two things I would try are: 1. If there is an application cache, clear it; and 2. If the application uses profiles of any kind, try a new, blank one. Related to those, you could create a new regular user, and log in as him/her, which should give a "blank slate" to test from. Lastly, purge the application and all config files and re-install (or just install Terminator or some such replacement).
