Hi,
  I maintain a Ruby gem that uses Cairo, and one of my users is reporting
an error that results in a CAIRO_STATUS_WRITE_ERROR being returned.
https://github.com/andymeneely/squib/issues/236

I haven't been able to reproduce the conditions myself, and the only times
I have ever gotten that was when I tried to write to a file that was being
held onto by another process. I'm confident that we've eliminated that.

What other conditions might you get a CAIRO_STATUS_WRITE_ERROR on a
cairo_write_to_png
call?

-Andy
