policycoreutils-gui applications icons shown in Gnome

Description of problem: Invoking "Select..." in "SELinux Configuration" opens a window closed; reported at https://github.com/SELinuxProject/selinux/issues/206

Version-Release number of component: policycoreutils-gui.noarch 3.0-2.fc32;
Environment: Fedora, Gnome on Wayland.

How reproducible:
Installed packages along with policycoreutils-gui; see gnome_applications_policycoreutils-gui.png

Those icons are respectively,

- named as follow:
icon 1 – SELinux Policy Management Tool
icon 2 – SELinux Policy Generation Tool
icon 3 – SELinux Management

- listed as follow:

$ gsettings get org.gnome.shell favorite-apps
['sepolicy.desktop', 'selinux-polgengui.desktop', 'system-config-selinux.desktop']

Applications associated to icons 2 and 3 can be launched from terminal:

$ selinux-polgengui
(selinux-polgengui:18273): Gtk-WARNING **: 14:47:15.482: Content added to the action area of a dialog using header bars

(selinux-polgengui:18273): Gtk-WARNING **: 14:47:15.482: Content added to the action area of a dialog using header bars

$ sudo system-config-selinux
** (system-config-selinux.py:18412): WARNING **: 14:50:54.820: AT-SPI: Could not obtain desktop path or name

** (system-config-selinux.py:18412): WARNING **: 14:50:54.822: atk-bridge: GetRegisteredEvents returned message with unknown signature

** (system-config-selinux.py:18412): WARNING **: 14:50:54.822: atk-bridge: get_device_events_reply: unknown signature

** (system-config-selinux.py:18412): WARNING **: 14:50:54.822: atk-bridge: get_device_events_reply: unknown signature

Actual results:
Application associated to icon 1, launched from desktop, has that process path:

$ ps -aux | grep -i selinux | head -1
root       18696  0.0  0.2 244012 20984 ?        Ss   14:58   0:00 /usr/bin/python3 -Es /usr/share/system-config-selinux/selinux_server.py

Invoking "Select..." there, "SELinux Configuration", opens a window that is immediately closed.

Attempts to launch that application from terminal fail. Launch is remaining in that state:

Expected results:
- Closed window to not be closed;
- Application launch from terminal to succed.
