Bug#515734: Another symptom
I think this is a different manifestation of the same bug (and the
same remedy, downgrading to libxi6 from testing, works).
I have the keyboard switching applet enabled in KDE. When I try to use
it in the sid version to change the layout from my default (se
-variant dvorak), nothing happens (the flag in the applet changes, but
the layout stays the same).
Additionally, and weirdly, both global shortcuts and the "Run command"
dialog seem to use 'us' layout, no matter what.
