I upgraded my packages, firewall-config and alike programs.

I tried loading up firewall-config through both YaST and the app menu.

Now when I try to launch firewall-config, it returns:
Execution of command "[["/usr/bin/firewall-config"]]" failed. Exit code: 1 Error output: Traceback (most recent call last): File "/usr/bin/firewall-config", line 8170, in <module> app = FirewallConfig() File "/usr/bin/firewall-config", line 1386, in __init__ self.connection_changed() File "/usr/bin/firewall-config", line 1692, in connection_changed self.update_active_zones() File "/usr/bin/firewall-config", line 2465, in update_active_zones connection, zone ]) File "/usr/lib64/python3.6/site-packages/gi/overrides/Gtk.py", line 1237, in append return self._do_insert(parent, -1, row) File "/usr/lib64/python3.6/site-packages/gi/overrides/Gtk.py", line 1229, in _do_insert row, columns = self._convert_row(row) File "/usr/lib64/python3.6/site-packages/gi/overrides/Gtk.py", line 870, in _convert_row result.append(self._convert_value(cur_col, value)) File "/usr/lib64/python3.6/site-packages/gi/overrides/Gtk.py", line 888, in _convert_value return GObject.Value(self.get_column_type(column), value) File "/usr/lib64/python3.6/site-packages/gi/overrides/GObject.py", line 218, in __init__ self.set_value(py_value) File "/usr/lib64/python3.6/site-packages/gi/overrides/GObject.py", line 274, in set_value (py_value, type(py_value))) ValueError: Expected string but got False<class 'bool'>
