--- Comment #4 from Michael Weghorn <m.weghorn at posteo.de> ---
"kts" has sent me the PDF file by email. Since it is a book, I am not sure
whether it might be copyrighted, so I don't feel confident of making it
available publicly.

I can reproduce the problem (with custom build of Okular's current master
branch, as of commit d150c10bce8b2e8b729fbae27a2072c31bcad9d3).

In fact, Okular does crash, there is a segfault when closing Okular (user might
not recognize, since they want to close application anyways).

gdb backtrace:

Thread 1 "okular" received signal SIGSEGV, Segmentation fault.
