"gall: missing" when nuking agent

[belisarius222]

>=
> |nuke %board
nuking agents will permanently delete all their state and subscriptions.
if other agents depend on the one(s) you nuke, their behavior could be negatively impacted. if you do not understand the risks, you may want to contact the agent's developers.
are you sure you want to continue and nuke %board?

I don't know if anything went substantively wrong here, but it's not clear to me that gall: missing is ever anything other than a bug in Gall.
