Error formatting disk "Error synchronizing after initial wipe: Timed out waiting for object (udisks-error-quark, 0)"

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Maybe the bug is in udisks2? https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=695473#66

Status changed to 'Confirmed' because the bug affects multiple users.

The bug is marked as closed in debian with util-linux (2.20.1-5.8), I have made some tests with it on my trusty environment, the timed out issue is still reproduced with gnome-disks or usb-creator.

If we ignore the timed out error in util-linux/src/udiskslinuxblock.c: handle_format():

  if (udisks_daemon_wait_for_object_sync (daemon,
                                          wait_for_filesystem,
                                          wait_data,
                                          NULL,
                                          15,
                                          &error) == NULL)
    {
#if 0
      g_prefix_error (&error, "Error synchronizing after initial wipe: ");
      if (invocation != NULL)
        g_dbus_method_invocation_take_error (invocation, error);
      else
        g_clear_error (&error);
      goto out;
#endif
    }

Then gnome-disks can format usb sticks correctly, and usb-creator also works with another patch:
