Status changed to 'Confirmed' because the bug affects multiple users.

[Matthias Klumpp (ximion)]

This issue is likely fixed in a more recent version of PackageKit, we changed the initialization part quite a bit, and the code in question now has a NULL check too.
Ideally, PackageKit should be upgraded to fix this.
(I'll discuss with the others once again...)

[Salih EMIN (salih-emin)]

This happens when I go System Settings --> Details. Apparently this is due to the "Overview" menu where it automatically searches for any available updates (packagekit).

I have the same problem, using Xenial 16.04 (X64).

Seems solution is to install python3-aptdaemon.pkcompat, which removes packagekit.

'sudo apt-get install python3-aptdaemon.pkcompat'

Same problem with ubuntu LTS16.04.
I noticed that on all reports I found concerning this bug, the architecture is amd64.
pureadmin version(0.4-0ubuntu2)

Sorry, I didn't find how to modify my previous comment. As I have not packagekit is not installed, I don't think it is a duplicate of bug #1572778.
