deja-dup does not start

[Jarkko Toivonen]

Hi,

I have installed deja-dup backup program under Cygwin, but it does not 
start up.
It shows the message shown at the end of this mail, but no window appears. I
have X11 installed and it is working correctly.
Looks like it is a problem with dbus. How to solve this problem?
And what does that message "you must specify a mode" mean?

dbus-daemon seems to be running as well:
$ ps -ef | grep dbus
    huipp    1004       1 ?        19:27:04 /usr/bin/dbus-daemon
    huipp     971       1 ?        19:17:58 /usr/bin/dbus-daemon
    huipp     951       1 ?        19:17:35 /usr/bin/dbus-daemon
    huipp    1016       1 ?        19:27:35 /usr/bin/dbus-daemon
    huipp     949       1 ?        19:17:35 /usr/bin/dbus-launch
    huipp    1022       1 ?        09:40:09 /usr/bin/dbus-daemon
    huipp     998       1 ?        19:22:36 /usr/bin/dbus-daemon
    huipp     977       1 ?        19:20:26 /usr/bin/dbus-daemon
    huipp    1010       1 ?        19:27:13 /usr/bin/dbus-daemon

Best regards,
Jarkko

Déjà Dup is a simple backup tool.  It hides the complexity of backing up
the Right Way (encrypted, off-site, and regular) and uses duplicity as
the backend.
