bug#41489: `package-dir-info' fails on a directory with a non-saved file

[Paul Pogonyshev]

I also noticed that the error depends on the Moon phase, i.e. it is not _always_ reproducible. The reason is that it depends on the random order of elements in `(directory-files default-directory t "\\.el\\'" t)' result.

Sorry. In any Emacs version. I tested with a fairly recently compiled `master', but judging by the source code I checked out two minutes ago, the bug is there currently too. The cause is this:

            (insert-file-contents (pop files))

This form is not inside `(ignore-errors ...)' and so any failure is propagated out of `package-dir-info' too.

In what version of Emacs is that?  Please always supply the
information collected by report-emacs-bug, as that saves unnecessary
questions such as this one.

Thanks.
