apper search doesn't provide any results

[Karl-Philipp Richter]

Search for terms which definitely should return a result, like `linux` or `apper` don't display any. The progress circle is displayed for half a second and then disappears. Every search request creates a message on the terminal in the form of

    QDBusConnection: name 'org.freedesktop.PackageKit' had owner '' but we thought it was ':<x>'

where `<x> is an increasing number.

Is this still an issue on Ubuntu 18.04?
