This could be solved by bug 1722967

[Ihar Hrachyshka (ihar-hrachyshka)]

It's probably a different bug, since I don't see the error message from that other bug when the test case still fails, and afaik the failure is older than the patches that introduced that other regression.

Closing as we don't see the issue anymore. Trunk tests failure is now tracked in bug 1740885
