[binc] spurious login failed message on session timeout

When a logged in session gets timed out, binc is sending through a login 
failed notice:

I noticed Peter raised this a short while ago:

http://www.bincimap.andreas.hanssen.name/archive/?1::687

Did anything come of this?

I'm running bincimap-1.2.12final. Apologies if this has been fixed in 
1.2.13.  I've not upgraded as there was nothing in the change log 
(http://bincimap.org/dl/ChangeLog) my environment would have benefited from.

thanks,
