Impossible to type "ù"

[Pétùr <peturvilj@gmail.com>]

Hi,

I cannot type "ù" anymore on Debian Xfce Sid (French keyboard).

All other accented character (éàûè) work but the cursor just blinked 
when using the dedicated key for "ù".

Any clue?

I tried different keyboard configuration with

# dpkg-reconfigure keyboard-configuration

the current one:

# cat /etc/default/keyboard
# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.
