@mucek4 Please have a look at the problem.
It fails reproducible.

I did a "retest this please" on #8340, and this time the tests finished flawlessly, although running on cgeo-4. Strange.

But for https://ci.cgeo.org/job/cgeo%20pull%20request/2807/ it failed again, although only string updates from crowdin were included in this PR.

cgeo-4 is a docker, running on server in my home. I have added some other docker containers on the same machine in past 14 days. I'll check what we can do. We have to also solve cgeo/cgeo-executor#15 As right now that image is the only one working.
