avoid predictible crashs

Asked by Arnaud Schmittbuhl

Hi all,

it's a feature request.
I recently stumbled upon a (temporarily) strange trouble.
Someone sent me some pdf files I tried to open with qpdfview. It crashes
every time with a "segmentation fault" message.
It took me some time to discover that the so called pdf files were
in fact... html files!
So, could it be possible to make a file format verification before
trying to load the file and adjust the error message accordingly?

Thanks à lot,

Hello Arnaud,

thanks for taking the to report this. There is actually is a content-based format check in place, either using libmagic or shared-mime-info depending on whether Qt4 or Qt5 is used. In any case, if it crashes it is a bug. Even with malformed documents, the program should crash. Even they look like PDF internally but a just corrupt.

So could you: Open a bug report about this and attach such a document? Also could you specify which distribution, package, etc. you use? Thank you!

Best regards, Adam.

Can you help with this problem?
