This is more of a tracker bug than anything else since dilfridge (and me) are already on the bug. More info here: http://mailman.verplant.org/pipermail/collectd/2011-July/thread.html#4608 upstream patch here: http://octo.cx/5ec7a37 (btw dilfridge, feel free to add me as a proxied maintainer if you find it appropriate)
I had to fiddle with the patch as it did not apply cleanly, please test and check that it works as expected. But- it should be fixed. I've added you as proxied maintainer, thanks for the offer.
