Running emacs with the golang-mode package freezes after selecting text with the cursor, then using CTRL-y to paste it

I suspect the proble lies with the golang-mode package, since I do not see this behavior when using emacs to edit python source code or plain text.

As I described in the summary, copying by selecting text with the mouse, followed by typing CTRL-y to paste it causes emacs to freeze; it does not respond to any more keystrokes, and the mouse does not work either.

The only way to close it is to find the pid and send it a -9 kill signal.
