The kid could not tell, but he said that Sugar dies like this sometimes. Any idea how this DBus error could be triggered?

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "GetProperties" with signature "" on interface "org.laptop.Sugar.Presence.Buddy" doesn't exist

Also maybe #2064 could be relevant, if we happen to do the same thing that we were doing in the Journal.

We seem to ask for the properties of a buddy that is not on the bus any more. Should be relatively harmless.

Replying to tomeu:

Ok. We shouldn't trap the exception to avoid printing a backtrace?

How about this other error?

We should listen in the bus so we know when that name is not available any more and update our model. Which is what Aleksey did for the activities.

How about this other error?

{{{

This is what Aleksey fixed in #2064.

This is very likely a duplicate of #2064.

Tincho could you please attach the logs you collected today? (if they are relevant to this bug and bring anything new)

  Changed 2 years ago by bernie

  • status changed from assigned to closed
  • resolution set to duplicate

Closing as duplicate of #2064 as we're obviously not going to diagnose this further.
