The problem is tickled by the continuously updated text in the buffer,
but I have no idea why it's happening.

If I have `transient-mark-mode' switched on, and you `M-w' a line from
the article buffer, I get the following:

(car kill-ring) =>
"diff --git a/lisp/ChangeLog b/lisp/ChangeLog
"

Which is correct.

(x-selection-value-internal 'CLIPBOARD) =>
"diff --git a/lisp/ChangeLog b/lisp/ChangeLog
"

Which is also correct.

(x-selection-value-internal 'PRIMARY) =>

Which is WTF?!

The latter wins, so when you yank the text, you get that instead.  It's
not random what you get, it but it's not what you killed.

Does anybody who knows more about the Emacs kill'n'yank internals know
what this could mean?
