Subject: 24.0.50; Can't yank text on Mac OS X
Date: Thu, 22 Jul 2010 11:31:27 +0200

Running Emacs from bzr on Mac OS 10.6.4, if I mark some text, save it
with M-w, and then try to yank it with C-y, I get the error message
'Quit: "pasteboard doesn't contain valid data"'.  (See keystrokes and
message log below.)

Also, I can't paste the saved text into another application.  However,
if I copy text from another application, I can yank it into Emacs with
C-y.

Only M-w and C-w seem to be affected; text killed with M-d and C-k can
be yanked and pasted.

Everything used to work as expected in Emacs 23.2.

Correction: I figured out that the nature of the problem is different.
When I mark a region of text with C-SPC and movement keys, everything
works fine if I then hit M-w _twice_.  After the first press, the
highlighting disappears, and after the second press, the cursor briefly
blinks at the mark, signalling that the text was actually saved.

I'll dig deeper into this when I find time...

Hmm. Not that it helps you exactly, but that's actually a bit less 
broken than I thought.  Please note, there are several known issues in 
this area on macosx and other platforms owing to some recent changes to 
defaults.

see e.g. #6677 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6677

See:
http://lists.gnu.org/archive/html/emacs-devel/2010-07/msg01314.html
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6720#20

for instructions on reverting the new behaviour for now if you want to.

I will be looking at the area over this weekend, anyway, on x11/w32/ns.
