Public bug reported:
Press Ctrl+Shift+U (start entering a Unicode character by its hex code),
followed by seven alphanumeric characters.
The keyboard stops working. It's no longer possible to enter any keys
into any application, making the system completely unusable. (Tested
with gnome-terminal, firefox, gedit, konsole, xterm.)
Unity shortcut keys (Alt+Tab etc.) still work.
The keyboard layout switcher (Alt+Shift for me) works and resets the
keyboard so it's back to normal, although it shouldn't be required, and
many users probably don't have such a key defined, or wouldn't figure
out they need to press it after the lockup.
Side note: After Ctrl+Shift+U, not only hex digits but any letters are
accepted and accumulated as the hexadecimal character code, this doesn't
make any sense to me.
