No, it's a different bug: simply moving back and forth
a symbol file between the current directory and a directory
completely changes the scale of the output file (by a factor
a several hundred or several thounsand, I can't remember).

In the case I hit the bug, the frame of the titlepage occupies
at most 1mm˛ on the paper, and most of the page is white. I've traced
it to cairo_recording_surface_ink_extents() returning nonsense,
but could not go further.

I'm aware of it, but I also hit a bug in it (locally fixed).
