[Aptitude-devel] Bug#815810: "aptitude show pkgname" does not display information about non-installed packages

[Awal Awal]

Package: aptitude
Version: 0.7.6-1
Severity: important

Dear Maintainers,

Upgrading to aptitude version 07.6.1, aptitude does not show information
about non-installed packages.

"aptitude show non-installed-package-name" returns "Segment violation
(`core` generated)"

Thanks for your work,

Awal
