The ia32-libkrb53 package is the stable one, ia32-libgssapi-krb5-2 is
testing/unstable. The user is installing the replaced packages after
the replacing package. But dpkg should handle that.

% dpkg --compare-versions "1.6.dfsg.4~beta1-5lenny1~22" "<<" "1.6.dfsg.4~beta1-7~22" && echo yes
yes

The version dpkg tries to unpack is smaller than the one in the
replaces.
