            Bug ID: 439724
           Summary: Check first if ghostscript is installed before
                    generating a preview which cannot be displayed or
                    printed anyway
           Product: okular
           Version: 21.04.3
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: postix at posteo.eu
  Target Milestone: ---

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
