Dia 0.96.1 (only PDF), 0.97 or current master should all work to reproduce.

Now I have a dia file with only two boxes and a line which makes cairo go 
into that endless loop. I'm attaching the cairo-script file created with 
Dia's new cairo-script export facility ;).

But I wonder if the precision given by that file is enough to reproduce the 
bug. And I didn't find a way to check myself. csi-replay.c looked 
promising, but I can't find a binary created from it.
