Obvioulsy , these two bugs are indeed the same one.

Evgunyi pointed that this is probably a
problem in the whiptail library when working in a UTF-8 environment.

I'm a bit reluctant at reassigning it to newt or whiptail until
someone is really sure it belongs to it. Please do if you're sure of this

I'm giving this an "important" severity as in case the user
inadvertently hits a "wrong" key, which is likely to happen on non-US
keyboards, the installer is *apparently* frozen. In fact, it is not,
but the way to get out of it is really tricky.
