I'm a Louis' coworker and I also worked on this issue.
We first did some tests starting from 2.12 to find a workaround with qemu-img. It seemed that this version of qemu was immune to our bug. Then, we backport packages from cosmic and reproduce our production issue.
I'm not familiar enough to qemu code and I was unbale to find the commit which fix the issue.
