That's interesting. So, a fix was required for builds on Ubuntu, but
not on Debian.

I built it successfully with sbuild on my local machine. I also did a
successful trial run on debomatic:

http://debomatic-i386.debian.net/distribution#unstable/ri-li/2.0.1+ds-4/buildlog

I understand Markus' frustration considering the package used to build
fine before, still builds ok now (works on my sbuild and on dom) but
fails with your setup, with no obvious clue as where the failure could
originate from. I feel in the same position regarding this issue with
src:python-qtpy and admit I don't know enough of the inner workings
behind xvfb-run to investigate it.

Assuming this issue were later raised to RC-level importance, then I am
afraid I'd have no option but disabling the tests to keep the package
running, if no one with relevant expertise is able to provide a patch.
