strange terminal-emulators-only behaviour: broken key-map?

[Simone]

hi,

 strangely it seems that *only* my gnome-terminal/xterm stopped to
correctly map my keyboard (pc105). Other applications (gedit,
openoffice,...) still work correctly.
For example, if I type shift+3, I should get the "£" character but I
get "#"+return and "èéàç" keys are no longer working, printing out
empty spaces. Same behavior in xterm or other terminals...
I also tried the "fr" layout with the same result: "£" is mapped to "#"+return.

How could I debug the problem? Any suggestion or useful pointers?

details
=======
- I'm running ubuntu 8.04.4 LTS
- gnome v.2.22.3
- gnome-terminal 2.22.1
- "locale" output[1]
- "setxkbmap it -print" output[2]


Thank you in advance,
 Simone
