Please describe the problem:
Go into Keyboard Preferences and start with the USA Layout
Add a new layout "USA Classic Dvorak"
Set Shift-CapsLock as the way to switch layouts



Steps to reproduce:
1. open gedit
2. Press CTRL-F (this should open the find dialog), press the F key it should show an f in the dialog
3. Close the dialog
4. Press Shift-CapsLock to switch into Dvorak mode
5. Press CTRL-F (using the US layout), the find dialog will open, but it should not because when you press the 'F' you get 'u'. 


Actual results:
See above

Expected results:
When in Dvorak layout pressing CTRL-F on a US non-Dvorak keyboard should issue the CTRL-U shortcut since on the Dvorak keyboard U is where the F key is on the keyboard. Since CTRL-U is not mapped to anything as a shortcut the dialog should not open

Does this happen every time?
Yes, and it happens in many other GTK applications as well

Other information:
This problem may be at the GTK/GDK level since appears in many applications. The shortcuts are not going thru the keyboard layout code.
