[Bug 1294877] Re: usb-creator fails to wipe usb device when the device has ext4 partition

[George]

Same problem exists with 32-bit architecture:

org.freedesktop.DBus.Python.gi._glib.GError: Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/dbus/service.py", line 707, in _message_cb
    retval = candidate_method(self, *args, **keywords)
  File "/usr/share/usb-creator/usb-creator-helper", line 239, in Format
    block.call_format_sync('dos', GLib.Variant('a{sv}', {'erase': GLib.Variant('s', '')}), None)
gi._glib.GError: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error synchronizing after initial wipe: Timed out waiting for object.

IMHO udisks is broken.  Exact same process works flawlessly under 12.04
with identical unmodified hardware.  Disk utility in the current release
is another example of this flawed behavior. Benchmarking works fine in
12.04 but udisks blows up spectacularly attempting the same process in
more recent releases. This is one of the rare occasions I wish to go
backwards.
