The endianness patch did not affect the xlib backend that you are using.
So if there is a changed behaviour it must have a different cause.
What is strange in your back trace is that both width and height of the
destination rectangle are 0 in this case we should never get to the line
where this claims to be crashing.
But then the x and y coordinates of source and destination are negative.
I have no idea how this could happen.
