@Clément Foucault (fclem), could it possibly be just P840? (fixes it for me...)

@Clément Foucault (fclem): nvm, for some reason I cannot reproduce anymore.
I guess rB1d4ad6819857 fixed this as well [and there was just some issue with rebuilding that on my side...]

So @Catalin (giakaama), this is probably fixed by above commit, could you check latest buildbot build?
Closing (but feel free to reopen if issues persist)

@Clément Foucault (fclem) Downloading the latest now, I'll check if it still happening :) .

Thanx guys for your hard work .
