Detect/Open incomplete documents

[Razi Alavizadeh]

I have a DjVu document that is corrupted, currently when opening it qpdfview crashes.

Indeed crash is when "DocumentView::preparePages()" is in progress, because:
m_pages.count() is 547 but m_pages.at(index) for index > 141 is null.

I think
- At least: qpdfview should cancel loading document and notify user that the document is corrupted and not a bug of qpdfview.

- And it's better if: it loads document and shows suitable replacement for pages that are null.

Hello Razi,

trunk revision 1739 should take a more transactional approach and only load documents if all the indicated pages can actually be loaded. Please test that this handles the case you describe.

I am also firmly against trying to fix up or partially display broken documents as this invites all sorts of corner cases and I find not loading them in the first a much cleaner solution.

Best regards, Adam,
