May it be that you clicked the "eraser" button while being in the "summary" page, i.e in the page that is not part of your pdf that shows as page zero?
By the way, it has nothing to do with being run in Unity, why do you think that would matter at all?
Comment 1) No, I was in the middle of the PDF, on a regular page. Comment 2) I think it might matter because I did not install KDE (just the dependencies for Okular) so it is conceivable that there could be a conflict somewhere (especially as Unity does seem to handle some things a bit differently). I obviously don't know for sure, but thought it was a useful piece of information.
Can you reproduce the crash? I.e. do the same again and it crashes again?
Yes, I am able to reproduce it. It doesn't happen with all files though - the one that reliably crashes on 'erase' has some comments and text markup (from Acrobat) also. A simple PDF with no such annotations seems to be OK. I am also able to reproduce the effect also by opening a PDF, creating some notes and markup on it with Okular, then switching to presentation mode, making a few drawing lines, and clicking erase.

Is it possible for you to attach to the bug the file that always makes okular crash when clicking on 'erase'? That will make our lives easier trying to reproduce and fix the problem.
Created attachment 72022 [details] Annotated PDF for testing 'eraser' crash. This is just a regular PDF with some annotations on it.
I cannot attach the original file as it is a draft of a paper I am working on (unpublished). I have been able to replicate it with another file though, and have attached that. The conditions seem to be: 1) have more than one annotation in the PDF 2) draw several (~4?) marks while in presentation mode, then click on 'erase'. The program then crashes.
This has been fixed for KDE SC 4.9.0, unfortunately can't be backported to 4.8.x because of the core changes it needs in okular
