This fix applies cleanly to 3.4 and 3.5. 3.3 panics, which IMHO is a valid "response" as well.
Jeremy, can you please review, possibly ack and re-assign this to Karolin?
Thanks to Laurent Gaffie <firstname.lastname@example.org> for pointing out this crash to us!
+1 from me. Re-assigning to Karolin for inclusion.
Karolin, can you give Laurent Gaffie <email@example.com> credits in the WHATSNEW.
Pushed to v3-5-test and v3-4-test.
Closing out bug report.
