Has this started appearing on the bots just recently? The issue has been there for long when I ran the tests in my computer.

No, it's been happening for ages. But I changed criticals to be fatal yesterday to reflect the severity of these bugs, so only now are the tests crashing.

By the way, half these tests were already failing anyway. The test expectations are starting to become a bit messy as I've now filed a second bug report for many multimedia tests that previously had only failure bug reports and now have a second crash bug report as well. That started a couple weeks ago, not just yesterday. Really not pleased about the state of our multimedia tests. :(

It's fine by me as long as the patch is submitted upstream. Enrique, can you review it please?

This is being tracked in GStreamer bugzilla here: https://bugzilla.gnome.org/show_bug.cgi?id=782217 The patch looks good to me, but could you please submit the original gst-plugins-good patch to the bug above?

The patch has been approved upstream. In the meanwhile until the next stable version is released we should commit the patch internally for our jhbuild so we stop getting stderr in our test runs. You may want to consider this upstream commit from Sebastian when doing so: https://github.com/GStreamer/gst-plugins-good/commit/728a1629cf9fd7f4a728477bda1d13a1ecc219bb
