Comment 4 for bug 1770129

@Walter Lapchynski
"Everything otherwise works fine"; surely not. For example, the installation program of hplip just crashed with "GLib-GIO-CRITICAL **: 16:14:04.867: g_dbus_proxy_new: assertion 'G_IS_DBUS_CONNECTION (connection)' failed" after the GUI dialog screen was launched and I pressed <Continue> (the error message was repeated three times and the installation program hanged up). I restarted the installation choosing "interactive" instead of "GUI" (which was the default choice) but I had to uninstall the previous failed installation, which had already written stuff on disk etc.
I would expect that any installation or script that launches a GUI from terminal would be affected.
At any rate, the bug makes for extremely bad publicity for Ubuntu and Linux. It's a CRITICAL error that keeps coming up; as if the aircraft's rocket engines sputtered and stuttered all the time but the crew tried to reassure you by saying, "don't worry, everything otherwise works fine". Some googling shows that quite many people are affected by the bug, both in Ubuntu and in other distributions.
In my opinion, this should be high on the priority list.
