Created attachment 60380
  --> https://bugs.freedesktop.org/attachment.cgi?id=60380
sample .pptx

So, with the attached .pptx around slide 20 we end up doing...

XCreatePixmap (dpy=0x202e400, d=<optimized out>,width=187690, height=187580,

which will fail cause that's just way too large

I'm stumped by this one, but I attach a debugging patch and some debugging
output and I think the massive numbers come from Shape::createAndInsert
