@Guillaume, was "4.1" a typo?

As for the possible resolution for this, it seems a patch was indeed
written and merged in master, in which case I will wait for the next
release and upgrade.

I don't think there's any real solution to avoid this bug until the next
varnish release, but, if there is, I'd love to know since this happens
quite regularly on my end.
