It could be, though I have only updated Emacs in the last ~10 days.

What seems to be the issue is when a deleted entry of the same name
already exists.  I emptied my trash and tried the above recipe: the
problem would not occur.  But upon immediate retry the problem appeared,
presumably because "test" already existed in the trash.

No

Yes, it does.  Both for my original recipe and with the other case I
mentioned above.

I have always set this to nil, which makes it use the trash of
freedesktop.org.
