[Aptitude-devel] Bug#815978: aptitude: 'aptitude show' segfaults on some packages

[anabioz34]

Subject: aptitude: 'aptitude show' segfaults on some packages
Package: aptitude
Version: 0.7.6-1
Severity: normal

Dear Maintainer,

Sometimes, 'aptitude show' lead to 'Segmentation fault (core dumped)'
(exit-code 139). For example, aptitude show unattended-upgrades. I tried
to update packages list, but it did not give any effect. This bug is
rare and does not affect most of the packages.
