Closing an application crashes Compiz

Starting Compiz on the command line, that's the last line I see before the crash:

** (<unknown>:5543): WARNING **: Unable to fetch children: Method "Children" with signature "" on interface "org.ayatana.bamf.view" doesn't exist

I see two possible explanations for this bug:

 a) One of the signal handlers on the BamfView "closed" signal frees priv->path, or perhaps more likely:

 b) There is exactly one ref on BamfView and there's a signal handler on the "closed" that drops the ref. This would make the priv memory block invalid.

If it's not any of that, then I'm stumped :-)

its b) thank you mikkel... now to fix it

Hernando: I filed another bug yesterday where the same output is shown; the action to reproduce might be different but the root cause of the two could be same:

  ""org.ayatana.bamf.view" doesn't exist: compiz/unity reliably crashes while loading Evince
  bug #683932

Is this still occurring with the latest unity and compiz?
