[Bug 2055402] Re: Though lintian call: error: troff: Segmentation fault

[Alexandre Erwin Ittner]

I got the same issue days ago when debugging a package in s390x, so it
is not architecture-specific.

The apparmor profile issue was a nice catch, I was getting some trouble
to reproduce it in a minimal fashion, but that was because I was leaving
the pipeline just output to stdout.

Should we patch lintian to only write this to /tmp ?
