Keyboard shortcut for Terminal doesn't work since updating to 12.10

Question

I have Ctrl+Alt+T assigned as my keyboard shortcut to launch a Terminal window, but it stopped working after upgrading to 12.10.

I have verified that it is still set in the Keyboard Shortcuts settings menu, and have verified that other shortcuts (e.g. Ctrl+Alt+C to open calculator) work.

I have also tried using assigning different key combinations to Terminal, to see if that helps (it doesn't), e.g. unassigning Ctrl+Alt+C from calculator, and instead assigning it to Terminal. No dice.

Any ideas what might be going on?

Solution

Solved it on my own, after having an idea sparked by @Mrokii.

In the Keyboard Shortcuts menu, I went to the Custom Shortcuts section, and added a new shortcut assigning Ctrl+Alt+T to the command gnome-terminal. This works!

There must be something screwy with my settings for default terminal... But I'm not going to worry about that, so long as my shortcut works.

Have you tried to start the app to set shortcuts via Bash? So you might see error messages if there are any?

that would be a good idea, but i haven't a clue what that keyboard shortcut menu's command is... no commands that start with keyboard-, and nothing under gnome- that seems to be keyboard related...

oh, solved it on my own though! your comment sparked the idea of adding a trigger for a custom command -- in this case, i explicitly called gnome-terminal; this works.
