This caused tons of failures in our automated testing, e.g.:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/78/builds/1630
https://autobuilder.yoctoproject.org/valkyrie/#/builders/2/builds/1606
https://autobuilder.yoctoproject.org/valkyrie/#/builders/60/builds/1601
https://autobuilder.yoctoproject.org/valkyrie/#/builders/19/builds/1599

but many more in that build too.

Cheers,
