Public bug reported: Mako, image 50 + manual unity8 update (7.84+14.04.20131206.1-0ubuntu1).
Just press the power button quickly to blank/unblank the screen, and unity8 will crash with the following: Program terminated with signal 6, Aborted. #0 __libc_do_syscall () at ../ports/sysdeps/unix/sysv/linux/arm/libc-do-syscall.S:44 44 ../ports/sysdeps/unix/sysv/linux/arm/libc-do-syscall.S: No such file or directory.
