It is clearly not layout related, as the French layout has the same
problem.

In the console it works.

My wife experiences the same problem.

So I don't know exactly if it is X related, or KDE, but my guess is KDE. I
don't have gnome installed, and I don't know how to identify the source of
the problem.

But since xev returns different codes for left and right alt, I think it
is the keyboard layout thing's responsibility to know that when after
ALT_R a v comes, it should produce the @ glyph.

Please have a look at this xev output, and tell me if it is good or not
(shouldn't state be different for the two alt keys?)
