Application stuck when trying to open a pdf book

[polarene]

I was trying to open a pdf version of a book but the app got stuck and the wheel spinning. Had to force quit.
I cannot share the file, since it's under copyright, but only some details about it, I'm sorry.

Hey, thank you for your feedback, but it's difficult to debug without a test PDF.

I know, I'm sorry about that but as written above I cannot upload it for copyright reasons
