[Aptitude-devel] Bug#963667: Aptitude segfault when user lacks read permission

[Gert Robben]

I have the same outcome, but I don't know if it's the same cause.
Anyway, I found aptitude segfaults, when the active uid cannot read some 
file.
Reproduce:

$ whoami
gert
$ su -c 'touch /etc/apt/preferences.d/test'
$ aptitude search nouveau
(works fine)
$ su -c 'chmod -r /etc/apt/preferences.d/test'
$ aptitude search nouveau
Segmentation fault

Maybe you have the same problem?
But I use stable, not testing.
