unity-panel-service crashed with SIGSEGV in ffi_call_unix64()

[Dclaw]

Bug occurred on login when trying to open some basic applications (firefox, xchat, pidgin)

Possibly related: my HDMI screen (I have dual monitors) has lines running through it causing all text to be slightly disjointed. This started after updates run yesterday morning. And it shows up when reaching the login screen. My DVI monitor does not have this issue.
