Status changed to 'Confirmed' because the bug affects multiple users.

[Edwin Pujols (edwinpm5)]

Happened to me while using trusty (installed on hardware). I had press `Ctrl+Alt+T`. I have Caps switched with Escape, and a second (Spanish) locale.

[Ads20000 (ads20000)]

Still applies in Utopic.

[richud (richud.com)]

Same problem for me in Utopic since upgrade, happens on each login.
Error popup says its a duplicate of bug 1380982 which doesn't exist? (https://bugs.launchpad.net/bugs/1380982
