Version: (using KDE 4.2.0)
Installed from: Debian testing/unstable Packages
In System Settings -> Keyboard & Mouse -> Global Keyboard Shortcuts -> Kwin -> Switch to Desktop 2.
When i set this value to Alt+É, the shortcut not operate. Perhaps because it should be Alt+é. I don't know is case is important. When i export and manually change the value to Alt+é in config file (.kksrc) and re-import into System Settings, segfault.
Alt+é is on french mapping equivalent to Alt+2 on english mapping.
Others "Switch to Desktop n" are functionnal with Alt+&, Alt+", Alt+'.
Meta+Shift+Tab (displayed in Meta+Backtab), is also not functional for "Walk Through Desktop List (Reverse)".
also tested on kubuntu jaunty (same issue)
