Same problem here. But for me, it happens whenever I open a LibreOffice application. I'm using Ubuntu GNOME Vivid Vervet.
It started to happen after installing fglrx drivers and reverting back to xorg ATI drivers.
I don't know which log files might be useful, but I can replicate the problem reliably here and I can produce any log needed.
