Bug 140117

Version:           3.5.5 (using KDE 3.5.5, Kubuntu (edgy) 4:3.5.5-0ubuntu3)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-10-generic

Hi,

I just stumbled over this scenario:

- reproducable: sometimes
  (perhaps it depends on some exact download percentage)
- Firefox downloads "call for paper (.pdf document") from http://emc06.powweb.com/emc2007/pages/papersub.htm
- Konqueror is opened in the target directory
- while the download happens, I move the mouse cursor over the PDF
-> crash:

It seems Konq's preview feature cannot sanely cope with broken (as in: not yet downloaded) PDF footers. Maybe some (more?) sanity checks can be implemented here?

Thanks! :)
