Well spotted, you are correct. Looking at apt/history.log and the timing
of my uploads, I must have run autopkgtest successfully with virt-qemu
and python3.7 3.7.1-1 while I was preparing flatpak 1.1.1-1.
The correlation with 3.7.2~rc1-1 seems very reliable, but I don't see
anything in the Python 3.7 news that looks like a likely trigger.
To be clear, I think this was always an autopkgtest-virt-qemu bug,
and I don't know why autopkgtest-virt-qemu worked so reliably in the past,
or why it still works with python3.6.
