Inkscape imports PDF such that contents can be displayed but not printed

[1448412]

Steps to reproduce:

1) Import the attached PDF document by using inkscapes own libraries.
2) "Print"
3) Look at the preview: All the text that was in the document and even parts of the logo now are gone. Problem also occurs, when exporting PDF via "File -> Save As".

Expected behaviour:
o) Documents, no matter if imported to or generated by inkscape are printed and exported as seen on screen.

Erratic behaviour:
o) Parts of the document are missing on print preview and when exporting.
