Comment 4 for bug 1764555

The repro fails complaining about an invlaid treeish even thou it is in the repo you mentioned.

# OS=debian ARCH=armhf DIST=stretch pbuilder-ev3dev dev-build
gbp:info: Building with pbuilder for stretch:armhf
gbp:error: upstream/3.2.0+dfsg is not a valid treeish

I was trying to run that on qemu 2.11.1 and 2.12 as I'm pretty sure - just like the older bug - this is an upstream and not an Ubuntu specific issue.
But without being able to verify that I can't yet reasonably add the upstream qemu task.

Can you by any chance build qemu from git and try with that?
