Firefox 3.5 does not allow to type unicode characters

Binary package hint: firefox-3.5

Upgraded to karmic beta, and got a new firefox 3.5.

When I enter unicode symbols into the text box from the keyboard, they
are not being entered (i.e. WIN+c in my layout pastes © in the terminal,
but not in the browser editboxes/textareas). Copying the symbols from
the terminal and pasting to the editboxes works okay (as you can see,
I've managed to copy the © symbol)
