Travis-ci-.org to travis-ci.com migration of github hosted qemu failed

I had a travis-ci.org configure for my fork of QEMU on github. It stopped working recently because now it is travis-ci.com. Ok, fine, go there, authentificate and everything but I cannot get travis-ci.com see my QEMU fork. If I select “all projects from github”, I see all of them (20+) except QEMU. If I select not all but only the ones I want (which is “QEMU”), the integration wizard says “ok” but the dashboard travis-ci.com is empty.

I removed the webhook on github for travis-ci.org. My QEMU fork is a public repo with default settings.What do I miss in this setup?
