This is very strange.

What does `apt-cache policy` say for all the relevant libraries?
(libc6, libpulse0, libsystemd-journal0, all in the i386 versions)

Perhaps you have another conflict in that is confusing everything. Please try:

% aptitude search '?broken'

To see if anything has missing dependencies on your system.
