Well, version 268 was just released, which fixes the xz issue ... but
introduces a test failure for 7z... which is worked around in the
attached patch.

The other option might be to package 7zip (which seems more maintained
than p7zip)... but that seems a bit longer term.

Yet another option would be to revert the patch that broke the test with
p7zip based 7z.

But for now I propose the workaround to effectively skip this one
test. :)

live well,
