              The file contains a separation colourspace that would appear isn't being handled correctly. The object number is 21 and looks like this.

              This is an interesting PDF only the "test" text is actually text everything else is a vector. The color issue appears to be related to PDF-694 and the application of transparency value to a color. In this particular case the tint value is 0.04 which is pretty much zero by most standards.
