I don't think we ever had such cases in practice.
Why is that bad or unexpected? If you install new software, it may have new dependencies. QEMU would be no different from other software there. Yesterday Eduardo said it was about having a fixed version installed and therein switching from a legacy machine to a newer machine. In that case the dependencies existed ever since installation but were not immediately visible to the end user due to our stability guarantees.
