Bug Description

Hi,

while installing a fresh focal based laptop landscape did not install any package profile configure via landcape webinterface.
After debugging the code I found that the process landscape-package-changer gets a segfault while processing the deb-package for the profiles.
This immidiately stops when /usr/lib/python3/dist-packages/landscape/lib/apt/package/facade.py:365 from
```
        deb = apt_inst.DebFile(deb_file)
```
to
```
        deb = apt_inst.DebFile(deb_path)
```

That way apt_inst opens the deb-file on its own and landscape installs all profiles as expected.

Regards,
Andreas

The behaviour can also be reproduced by the following simple python-code and the attached package file which was generated by landscape:

```
$ python3
>>> import apt_inst
>>> apt_inst.DebFile('8081330.deb').control.extractdata("control")
b'Package: landscape-profile-3btf7rtf-printer-packages\nVersion: 5\nArchitecture: all\nMaintainer: Landscape Team <email address hidden>\nInstalled-Size: 64\nDepends: expect, lib32gcc1, lib32stdc++6, lib32z1, libc6-i386, printer-driver-cups-pdf, xsane\nSection: metapackages\nPriority: optional\nDescription: Landscape meta-package for profile printer-packages\n additional packages to support printing e.g. for Brother MFC-9465CDN\n'

>>> apt_inst.DebFile(open('8081330.deb')).control.extractdata("control")
 Segmentation fault (core dumped)
