It seems to be of a much reduced frequency compared to when this was originally reported and the traceback isn't accurate, we can't tell what the original file was :(. I'd love it if someone had a reliable reproducer for this, without one we're a bit stuck to know where this is coming from. 82454 3 richard.purdie 2018-12-08 21:56:45 +0000 Since these and various other fixes, we've not seen these warnings: http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=df63ae7edd544c5d86b549345ad1ca1c9deacc41 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=f33fb239d60953aa3014bf694ab6d115054e5ab5 (this is only ever likely to be totally fixed in master)
