Segmentation fault at "Go to page" button, only in specific book + saved words bug

[Szybet]

As in the tittle. I can provide the book on pv if you want to test it. Here is the GUI_DEBUG log:

Segmentation fault

Also for this line, why saved words doesn't work for me:

mount: mounting /opt/config/06-saved_words on /kobo/mnt/onboard/.adds/inkbox/.config/06-saved_words failed: No such file or directory

Once you said to format the usb storage becouse something doesn't worked, becouse i was tinkering too much. other config files recreated itself but saved_words doesn't

I got the saved words bug too here for some reason. Will try to dig and see what causes it. As for PDF, we need to dig deep into Qt's internals to understand why there is a segmentation fault for no apparent reason...

Fixed the PDF issue in 5a38ecdab3b4a198ec3cb709437ac03767f92f01.

I will test it and then close the issue if the problem is resolved
