[Python-modules-team] Bug#917597: FTBFS: test failures

[Steve McIntyre]

Package: src:pytest-qt
Version: 2.3.1-2
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Hi!

I've been doing a full rebuild of the Debian archive, building all
source packages targeting armel and armhf using arm64 hardware. We are
planning in future to move all of our 32-bit armel/armhf builds to
using arm64 machines, so this rebuild is to identify packages that
might have problems with this configuration.

While doing that, I've found that pytest-qt fails multiple tests in
its testsuite. I've tested further and I can reproduce the same thing
in a normal amd64 build too, so it's not an architecture-specific
problem.
