Looks like mod_bucketeer is the culprit.
It fails to remove itself from the filter stack on EOS, and hence
makes a copy of the EOR bucket (as any METADATA bucket) for its own
brigade when it sees it.
Then the request gets destroyed twice (once per brigade it is in) on cleanup.

I fail to see where your patch comes into play here though, for now.
I also suspect EOR buckets shouldn't be copyable anyway, and bucketeer
should do the right thing, still the new filter should probably work
with the existing...
