Comment 3 for bug 1866881

I am not quite sure but since we are needing to carry this patch along new upstream releases this might not be just temporary. According to the DEP-3 headers this is an issue with Ubuntu builders:

Description: This test is probably using an already taken port on Ubuntu builder farm,
 it doesn't fail in Debian, in Ubuntu with sbuild on DebOMatic and locally.

I didn't spend more time investigating this since I noticed that the sync was a mistake and the previous delta fixes the regression. If you think more info is needed we can ask Gianfranco to chime in, and tell us the rationale behind this patch but I think the description is self explanatory.
