Brian,
I've reproduced your problem. From the initial review, it looks like there is
an issue with basho_bench and the way it assembles URLs. There also appears to
be a small problem with Innostore and key creation. We'll be investigating
these more and opening some bugzilla issues for them soon. I'll send an update
with links to those issues at that time so you can track the progress on them.
Thanks for the report!
