Test case

Reproducible here (kde  from GIT trunk).

Output in console:
(lots of)
okular(880) PDFGeneratorPopplerDebugFunction: [Poppler] "Error (1050250): Missing 'endstream' or incorrect stream length"

and a dozen og
GPL Ghostscript 9.05: Error: Font Renderer Plugin ( FreeType ) return code = -1

The second seems to be linked to an upstream bug in libfreetype version 2.4.8 / 2.4.9 [1]

If "Print preview" is used then okular crashes when closed. Follows backtrace:
Application: Okular (okular), signal: Segmentation fault

New crash information added by DrKonqi

okular (0.15.2) on KDE Platform 4.9.2 using Qt 4.8.3

The bug is mostly still reproducible with ghostscript 9.06, libfreetype 2.4.10, libspectre 0.2.7 and libpoppler 0.20.4:

1) The poppler bugs seem to be gone.

2) However, upon preview, Okular emits a couple of these:
  GPL Ghostscript 9.06: Error: Font Renderer Plugin ( FreeType ) return code = -1
so the libfreetype bug doesn't seem to be fully fixed.

3) And when closing, Okular crashes with the following output:

-- Backtrace (Reduced):

Are you guys actually printing the file? Because some of you complain about print preview but the subject of the bug says "Unable to print" not "Unable to print preview" or "Crash while print previewing"

It looks like the print issue is fixed, I am able to print the file now, however: the barcode is not printed correctly and  print preview doesn't work and crashes Okular on exit. Would you like me to report those separately?

Yes please open two separate issues.

Thanks :-)

> Yes please open two separate issues.

The barcode bug:
https://bugs.kde.org/show_bug.cgi?id=309729

The print preview crash:
https://bugs.kde.org/show_bug.cgi?id=309734

which is propably a duplicate of:
https://bugs.kde.org/show_bug.cgi?id=270602

Also I would like to point out, that the current Okular version is 0.15.3 and the highest version available on the bugtracker is 0.15.2
