Please attach the ps file that caused the crash
Comment 2 Manuel 2012-10-10 07:15:56 UTC 
Created attachment 74452 [details]
Source of the crash.
Comment 3 Albert Astals Cid 2012-10-10 07:28:35 UTC 
Does doing just a print preview crash?

> Does doing just a print preview crash?

No.
Comment 5 Albert Astals Cid 2012-10-10 17:18:34 UTC 
Can you describe in a clear step by step way what you did from opening okular to the crash?

Opening the file from Firefox. 
Click on File->Print->[Selected printer]->Print.

But it was not reproducible.
Comment 7 Albert Astals Cid 2012-10-14 20:30:28 UTC 
Git commit a0c398ea07090cfe2e8517f1a13c60789c444000 by Albert Astals Cid.
Committed on 14/10/2012 at 22:28.
Pushed by aacid into branch 'KDE/4.9'.

Only spectre_exporter_end if everything was successful

Otherwise we might end up crashing, of course this does not solve
why this error happened, but better getting an error saying something failed
than a crash .-)
FIXED-IN: 4.9.3
