[2023.5.0][armel] AssertionError: 0.0 not greater than 0 : max variance is strictly positive with IntegrationMethod(2d int, no split, CSC, cython)

[picca]

This error is trigged during the autopkgtest on the Debian infrastructure...

the main difference is thaht netwrok is available so it can download the images.

I have seen those tests failing sporadically for months, the bug must have been present since Jan'22

I believe this bug is fixed by https://github.com/silx-kit/pyFAI/pull/1923 If it does not show of again, I will close the issue in one month from now.
