Comment 2 for bug 1549582

This is the top of the stack for me after making it crash:

#0 0x00007ffff75c62d4 in meta_window_get_monitor () from /usr/lib/libmutter.so.0

It seems like line MultitaskingView.vala:513 is where it crashes. I seem to recall Gala crashing in the same line when using Multitasking View after closing a tab on Chrome and after using Alt+tab but I haven't been able to reproduce these consistently.
