How can this be reproduced? I tried installing libpango1.0-0 in a wheezy
chroot and doing a dist-upgrade to jessie, and that worked fine.

http://anonscm.debian.org/gitweb/?p=qa/jenkins.debian.net.git;a=blob;f=job-cfg/chroot-installation.yaml
indicates that this particular test case is:

"""
Debootstrap wheezy, then install four desktop environments and the most
commonly used applications and packages - and the build depends for all
of these, then upgrade to jessie
"""

... which seems inconveniently large.

https://jenkins.debian.net/ indicates that
chroot-installation_wheezy_install_developer_upgrade_to_jessie passes
or fails intermittently, and the failures don't seem to be related to
this bug.

I wonder whether this might have been the same apt issue
as <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=722912>.
Do you use wheezy's apt or jessie's apt (or something else, like aptitude)
for the upgrade? #722912 appears to have been fixed in jessie's apt.
