This question already has an answer here:
I use both German and US American layout. For convenience, I defined a shortcut to toggle these via Scroll. I also have an indicator on the top gnome shell bar that shows the current layout.
Yet recently, I assume it has something to do with the 13.10 upgrade, pressing the shortcut does not toggle the layout in the current application even though the indicator shows the change. Strangely, going into the keyboard applet via mouse and there selecting the layout works.
How do I get the keyboard shortcut working again?
