compiz crashed with SIGSEGV in unity::launcher::Launcher::Resize() from unity::launcher::Controller::Impl::EnsureLaunchers() from unity::UScreen::Refresh()

[Neal McBurnett]

While resizing an emacs window, I got this crash.

FWIW, I had just come out of suspend. Before the suspend I had a second monitor, taller but narrower, which was being displayed above this one. After the suspend I just had my laptop screen. The emacs window was automatically moved from the upper monitor to the laptop and was thus too tall vertically, so I had been moving the window around in that silly dance trying to

 1) move it to get the bottom aligned and
 2) get to the top to resize it down.

I also used the frame menu a few times to move and/or resize.

But who knows if any of that was related to the crash.
