I think the fix is:

I'm EOD - will pick this up tomorrow unless someone else wants to look
at it.

Title:
  [gtk-mir-backend] Clicking seems to confuse GTK (or the shell)

Bug description:
  Using utopic or current vivid, clicking on buttons/menubar in gtk
  application under unity8-mir leads to not working softwares.

  Not sure if that's the GTK backend or Mir to blame

  Small example attached, the program has a button and a label, click on the button should display "clicked!".
  Under unity8 the button seems to stop reacting after the first click and sometime the program closes

  (compile with "gcc button.c -o button`pkgconfig --cflags --libs
  gtk+-3.0`", to run it you need to have a .desktop running the binary
  and including the X-Ubuntu-Touch=true key)
