VirtualBox 1.6.4 broke my keyboard

[crotalus]

After upgrading VirtualBox from 1.6.2. to 1.6.4 the
keys / ? (slash - question) on my Dell Vostro 1400 laptop
stopped working. My keyboard layout is Protuguese(Brazil) - ABNT2.

To fix it, I just extracted the VirtualBox 1.6.2 rpm to
a directory and copied

/usr/lib64/VBoxKeyboard.so

onto the 1.6.4 version.

This has already happened in the past, according to this bug report:

This is the type of annoying bug that makes an installation
unusable for those who must use a shell to work.

Thanks.
