I did. I therefore didn't have "Encoded keyboard" turned on.
AltGr-E *crashed* Emacs again.

No, it's not possible. AltGr-e is the keysym e + the modifier AltGr; 
compose E = gets translated to the Euro sign by Xlib according to the 
Compose table.

I suspect something along the following lines: Emacs calls the 
function that translates input keysyms into a string, but does not 
envision that the resulting string will be several byte long for a 
single keystroke.

Something equally silly happened before with mice with more than 5 
buttons (dual wheel, in fact) : there was no check on the range of 
the button numbers returned by Xlib and Emacs crashed as soon as 
buttons 6 or 7 were pressed (i.e. the second wheel was moved).
