This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

with emacs -q
type any word, cut it, yank it a couple times
select the entire thing with the mouse
now yank still pastes only the word
while middle click (calling mouse-yank-primary) pastes the entire
selected text

Desired behaviour : yank should paste the same text as middle-click

x-select-enable-clipboard's value is t


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.

This is on purpose.  More specifically, this is the "standard X11
behavior" where mouse-selection and mouse-middle-click operate on the
PRIMARY selection, whereas cut&paste (aka kill&yank) operate on the
CLIPBOARD selection.

This was changed in Emacs-24.1.  Search for "Selection changes" in the
etc/NEWS file.  It includes explanation of what was changed and how to
revert some of those changes if you don't like them.  IIRC if you want
middle click to insert from the clipboard, you should bind mouse-2 to
mouse-yank-at-click.
