Bug#684148: libsvga1: Breaks multi-arch amd64 systems

[Daniel Franganillo <dfranganillo@gmail.com>]

Package: libsvga1
Version: 1:1.4.3-33
Severity: important

On my multiarch enabled amd64 after installing ia32-libs I got the next error message:

dpkg: error processing /var/cache/apt/archives/libsvga1_1%3a1.4.3-33_i386.deb (--unpack):

 trying to overwrite shared '/etc/vga/null.keymap', which is different from other instances of package libsvga1:i386

I think this problem is quite similiar as the one present in #676914

Thanks.
