File an issue against dbus-python monitor_dbus_signals.py not being informed PropertyChanged signals by callback

[mulkieran]

The evidence of the problem is here.

It appears to occur only when the script is run in the testing infrastructure.

The expected signals are always detected by dbus-monitor --system "path_namespace='/org/storage/stratis3'" run in a separate terminal.
