SUMMARY

On openSUSE by default there's no ghostscript installed (due to security concerns).
While this is an different issue, Okular always first tries to generate a preview, which, depending on the size of the document, may take some time.
In the end after wasting many resources it notifies the user that it cannot proceed since ghostscript is missing.

IMHO it would make sense to perform the check for ghostscript in the first place and if successful, generate the preview.


STEPS TO REPRODUCE:
1. Open document
2. File -> Print preview
OR
2. File -> Print
