Hi all,

A recent change in master (last 3-4 days) causes async package updates
using paradox.el to throw this error:

Debugger entered--Lisp error: (wrong-type-argument sequencep
#s(package-desc swiper (20170328 737) "Isearch with an overview. Oh, man!"

#<buffer *emacs*>)

The backtrace doesn't point to the part of paradox.el that causes this
error so I cannot debug it.

So a wild guess is that one of these is causing this issue:

f1d34d9136 * master origin/master origin/HEAD Minor cleanups related to
type-of
ab0a27517c * ; * lisp/emacs-lisp/package.el (describe-package-1): Tweak
recent.
fe8cf45710 * * doc/lispref/package.texi (Package Archives): Mention https.
f981c611e2 * Advertise https for homepage of gnu.org packages
048133d488 * Default to https for elpa.gnu.org if gnutls available
82b9efc869 * Minor simplifications and doc for records
12317ff4fb * Fix recent changes in record data type
604eb02fff * Make subprocess functions resolve the default directory
f4b50dad8d * Make ediff handle remote and quoted file names
2c68192c6b * Backward compatibility with pre-existing struct instances.
b6738682ae * Make the URL library use records.
8e6f204f44 * Make EIEIO use records.
0565482838 * Make cl-defstruct use records.
a2c3343029 * Add record objects with user-defined types.

Questions:

- Can anyone recreate this issue using async update using paradox using the
latest master?
- How would one debug using that backtrace?
