Hi Adrian,
This patch was merged, but it now looks like some of the added tests are
sometimes failing.
So far, we only saw the issue on test branches and never on master, so
there is a small chance some other patch is breaking the test, but I
suspect the issue is also present on master.
Here is the error:

Can you have a look at this? Any clue about what is going wrong here?
