That one looks like a race condition in port allocation. I don't think
this is the issue here, on my systems, the issue happens even when one
hasn't done anything for minutes.

That one seems more like it, but I cannot currently check the backtrace.
Will do as soon as I get the issue on a less important system. What
bothers me with this bugzilla issue is that the bug seems to be
presentin libvirt 3.0, not in libvirt 3.1, and then again in libvirt
3.2, judging from comment #3.

Guido, will we get libvirt 3.1 or 3.2 in unstable soon?

I have worked around the issue by setting autoport=no and assigning a
fixed port in the XML. Thankfully all my boxes have a dedicated, static
machine number so I was able to use this one to avoid collisions.
