Subject: 24.4;
 middle-click sometimes pastes data other than the PRIMARY selection
Date: Mon, 03 Nov 2014 21:56:44 +0100

Usually a middle-click pastes the PRIMARY selection, but sometimes
it pastes something else. I don't know how to reproduce this bug,
but it occurred several times in the last two hours.

Hi.

It seems I introduced this bug when fixing 16382.

The analysis that mouse-drag-track has something to do with this is correct, 
however it is not pop-mark, it is deactivate-mark who sets PRIMARY wrongly 
sometimes (pop-mark may itself call deactivate-mark).

I have checked in a fix in the emacs-24 branch.
