Dbus error on karmic

[Andreas Gros]

Dear all,

I get the same error running sugar (sugar-jhbuild version) in xephyr on 
Karmic as this guy on Jaunty (and which has popped up a couple of times 
before, I believe):
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/325706/comments/13

In my ~/.sugar/default/logs/shell.log it says:

1257976290.227409 ERROR dbus.proxies: Introspect error on 
org.freedesktop.ohm:/org/freedesktop/ohm/Keystore: 
dbus.exceptions.DBusException: 
org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ohm 
was not provided by any .service files
1257976290.228488 DEBUG dbus.proxies: Executing introspect queue due to 
error
1257976290.231768 ERROR root: Cannot unfreeze the DCON

One of the consequences is that the browse activity fails to start. The 
icon appears in the center, but at some point it falls back to the home 
screen.

Has anyone found a solution to that problem?

Thanks a lot

Andreas
