I have got two different backtraces, using the same ePub

Backtrace 1 : http://paste.kde.org/p0b9a1e1e/

Backtrace 2 : http://paste.kde.org/pa4e31b12/

I have noticed that it only crashes when the epub has an adequate amount of
images. Epubs with no images or 1 or 2 images are less likely to crash. The
more the images the more likely it is to crash.

Now we don't have to guess if it will crash on this file or not.
Considering all this, I have given you an ePub that is most likely to crash
atleast once before completing a round trip (top to bottom & bottom to
top).
