Bug#678225: libapt-pkg: Apt and related tools (apt-cache, aptitude, etc.) segfault on reading package lists
Package: libapt-pkg4.12
Version: 0.9.6
Severity: important
File: libapt-pkg
Dear Maintainer,
It appears that any apt- activity that depends on reading the package
lists is failing. (aptitude --version doesn't fail, aptitude update,
apt-cache policy, apt-get update, and aptitude show all do fail.)
