Gedit icon failed to show on launcher- inconsistent

[Nice Testhouse]

Release ubuntu 12.10 quantal (Radeon) with ppa:SIL2100

No gedit icon on launcher even though gedit windows are open. See attached screenshot.
This behaviour is not consistent, 2nd time I tried to open a gedit window and a gedit icon was visible on launcher.

Any specific pattern when this happens?

I cannot reproduce it on my system, maybe it's some bamf inconsistency.

I see exactly the same behaviour in Ubuntu 12.10 installed from CD and upgraded up to today (10 Feb 2013).

Gedit does not appear when switching applications with Alt+Tab either.
