Wow it's very strange that /usr/share/debconf/frontend segfault in such
conditions. It is a perl program.

While a version gap between libc6 and libc6-i686 could really cause such
causes of problem, the difference is very small in your case, and I
don't really see how it could cause such a problem.

Does a /etc/ld.so.nohwcap file exists when the versions of libc6 and
libc6-i686 mismatch (after a failure in the postinst script)?

That let me ask you a few questions:
- What's the output of ldd /usr/bin/perl in that case? and when the
packages are correctly installed?
- Are you sure there is a correlation between the segfault and the
presence of libc6-i686?
