Varnish 2.1.2 returning old version in cache

Hey there,
I found out that one of my varnish clusters (still running 2.1.2) responded
an old version of an object in between hundreds of requests.
The expected behaviour is an error 500, but somehow the object (which has a
60s ttl, btw) was returned. I wonder if this is a known bug that has been
fixed.
Here's my wget output (cleaned out a bit) in sequence:
