I tried this recipe, but I'm not getting the :filter function called at
all.  Do you have a recipe, starting from "emacs -Q", that reproduces
this bug?

And your report didn't include the data about the version generated by
report-emacs-bug, so it's hard to guess whether bug is only on some
specific system.
