apport-unpack crashed with ValueError in extract_keys(): ['separator'] has no binary content

[Luís Infante da Câmara]

(I am reporting this from the host: I tried to report this bug 6 times in the VM and it always logged me out.)

When unpacking a crash report (specifically that of bug #1981613), apport-unpack extracts most or all of the files correctly and then raises the following exception:

 Traceback (most recent call last):
   File "/usr/bin/apport-unpack", line 81, in <module>
     pr.extract_keys(f, bin_keys, dir)
   File "/usr/lib/python3/dist-packages/problem_report.py", line 244, in extract_keys
     raise ValueError(
 ValueError: ['separator'] has no binary content

Can you attach /var/crash/_usr_bin_gnome-shell.1000.crash to this bug report? Then this should be fairly easy to fix.
