Comment 5 for bug 1384503

I've attempted to reproduce this issue but I've not been able to at this point with stock 14.04 rsync versions between two 14.04 (up-to-date) systems. It may be highly dependent on the actual data; if you can reproduce this with something publicly available (like a large iso catted together multiple times or something else that I can create bit-for-bit); that'd help me narrowing down the fix.

Could someone who can reproduce this issue please run apport-collect 1384503 so I can get more information from the systems where you can reproduce?

W.r.t 3.1.1, we cannot backport the newer package into Trusty, see https://wiki.ubuntu.com/StableReleaseUpdates for the policy and rationale.

However, I will take a look at the changes in 3.1.1 to enable the new-style compression as well as the logic to detect when there is a mismatch; If that patchset is small and sane, we may be able to SRU just that change to fix this issue in Trusty.
