With master as I am writing this, I can reproduce with this recipe,
although the symptom has changed slightly.

An error no longer escapes to the command loop.  A message is printed:

tramp-error: Package `tramp-archive' not supported

The file foo.7z disappears from the Dired buffer.  Refreshing the buffer
(g) shows that the file has been renamed to bar.7z

Afterward in the same session, the bug no longer occurs.
