apport-bug compiz incorrectly detects Unity is running on Ubuntu 18.04 GNOME

[Wes]

Ubuntu 18.04 GNOME

To reproduce:
  - Reporting bug in compiz using apport-bug compiz

A dialog box pops up "Thanks for reporting this bug. It seems you have Unity running." (see screenshot)

Unity desktop is not running or installed.

Expected: apport detects that Unity is not running, does not show the dialog.

This is actually an issue in the apport-package hook provided by compiz. It contains the following:

 18 attach_gsettings_schema(report, 'org.compiz.core:/org/compiz/profiles/%s/plugins/core/' % current_profile)
 19
 20 unity_bug = False
 21 if ui and "unity" in report['GsettingsChanges'] and report['SourcePackage'] != "unity":

I guess using the gsettings_schema isn't accurate.
