While I'm not a mind-reader and thus don't know for sure, Rich's reference to 3.16 and compression might not be related to this bug at all. In 3.15 and early 3.16, there was a different bug related to compression, tho IIRC it was patched in 3.16.2 and 3.17-rc2 (or maybe .3 and rc3, it's patched in the latest 3.16.x anyway, and in 3.17). So how I read his comment was that he was considering going back to 3.16 and disabling compression to deal with that bug (he may not know the patch was marked for stable and is in current 3.16.x), rather than stay on 3.17, since this bug hasn't even been traced yet, let alone patched. Meanwhile, this bug makes me glad my use-case doesn't involve snapshots, and I've seen nothing of it. =:^) -- Duncan - List replies preferred. No HTML msgs.
