I found a workaround (fix?)!

framstag at diaspora:~: xbindkeys -k
Press combination of keys or/and click under the window.
You can use one of the two lines after "NoCommand"
in $HOME/.xbindkeysrc to bind a key.
"(Scheme function)"
    m:0x10 + c:24
    Mod2 + q

But what I have typed in was simple "q" and NO additional modifier key!
This means: xbindkeys sees a "Mod2" key, which I have not pressed!

I then added Mod2 to my .xbindkeysrc, like:

"xmessage xxx"
  Mod2 + b:12

And now it works! But why...?
