Bug Description

In bug #1661205 avahi-dameon repeatedly crashes, and causes apport to go into an infinite loop.

However I suspect this is a problem with apport, because when I manually unpack the .crash I get:

# apport-unpack /var/crash/_usr_sbin_avahi-daemon.0.crash /home/redacted/foo
Traceback (most recent call last):
  File "/usr/bin/apport-unpack", line 73, in <module>
    pr.extract_keys(f, bin_keys, dir)
  File "/usr/lib/python3/dist-packages/problem_report.py", line 270, in extract_keys
    [item for item, element in b64_block.items() if element is False])
ValueError: ['ProcEnviron', 'UserGroups'] has no binary content

Please find attached /var/crash/_usr_sbin_avahi-daemon.0.crash

It's worth noting that ProcEnviron and UserGroups are both empty.

I can reproduce it with the attached _usr_sbin_avahi-daemon.0.crash

Can you submit the crash by running "apport-bug /var/crash/_usr_sbin_avahi-daemon.0.crash"?
