Comment 6 for bug 1848556

Since it seemed so easy, while bisecting I found that it hangs with v4.0.0 and v3.1.0 from git and even v3.0.0.

Since the reported good version was 3.1 I began to wonder if I might have overlooked something.
I wondered if it might be e.g. the apache version providing a different behavior on http.

I was trying to access the same apache server with 4.0 and 3.1 and ran it against the download target:
$ qemu-img check https://download.fedoraproject.org/pub/fedora/linux/releases/30/Cloud/x86_64/images/Fedora-Cloud-Base-30-1.2.x86_64.qcow2

3.1 ran into a segfault and 4.0 seems to hang on that.
Maybe I should take a break and revisit that later, as people might have an idea already what this might be about.
