Description of problem: No amount of gconf tweaking is making my gnome-terminal cursor stop blinking. Neither the explicit 'off' setting, nor inheriting from the system's 'off' setting, turns off cursor blink. Version-Release number of selected component (if applicable): gnome-terminal-2.23.6-1.fc10.i386
I just tried, and unsetting /desktop/gnome/interface/cursor_blink in gconf did stop my gnome-terminal cursors from blinking...
I assume this works for you. If not, reopen...
