bug#12422: 24.2.50; package-list-packages fails on Cocoa GUI build

[Robert Dallas Gray]

[This only affects the Cocoa/--with-ns build]

./Emacs.app/Contents/MacOS/Emacs -Q
M-x package-list-packages

Modeline says 'Contacting host elpa.gnu.org:80', then nothing happens
until the command is cancelled.

This doesn't affect the X or gtk builds from trunk; nor does
it affect the -nw version of the Cocoa build.

24.2 release version works fine, and I've also tested the revision
tagged as 24.2 on the git repo
(http://git.savannah.gnu.org/cgit/emacs.git/commit/?h=trunk&id=efd2cb93e8db6256047b0cb8f1cc301ed2d0581a),
which works too. The revision immediately following that in the git repo
(http://git.savannah.gnu.org/cgit/emacs.git/commit/?h=trunk&id=83bdbf6e2253ba7e1a6ca2e9acfb86bdf09609d1)
exhibits the bug. The git revisions don't seem to exactly match the bzr
ones though.
