Installer crashed choosing Mac keyboard

[Ted Lemon]

Binary package hint: ubiquity

During installation, I'm offered the option to choose a keyboard variant. I chose Macintosh Keyboard. The installer crashed.

Here's the error message (I'm retyping it, so it might be slightly inaccurate):

Traceback (most recent call last):
  File "/usr/lib/ubiquity/ubiquity/plugin.py", line 44, in wrapper
    return target(self, *args, **kwargs)
TypeError: on_keyboard_variant_selected() takes exactly one argument (2 given)

It says to attach various files, but that seems impractical under the circumstances.

I'm installing under VMware Fusion 2.06 on an Intel Core 2 Duo Macbook Pro.
