Comment:

 I'm not sure about how to reproduce this bug, but I'm getting this error:
 {{{

 and this one too:

 I don't have too much experience with collaboration and dbus, maybe
 another person could help us. Could it be related with sugar itself? I'm
 asking this because we didn't touch the collaboration code after the work
 done in the ticket mentioned on the description.
