I saw the crash only on close, but maybe kts can say more.
(I just reproduced the issue on close quickly without any further testing.)

The crash is only on close, right? or can someone else reproduce a crash in any
other time?

Note: Segfault also occurs when using Poppler's current master branch (as of
commit c9958ecb87de34b923a17521c8bb149569bacca8).

"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.

I don't know whether there is an "official" way of sharing files that cannot be
uploaded here.
In general, you can upload the file using any service of your choice and add a
hyperlink here.
(You can also send me the file by email and I will do that, without the
guarantee that the file will be available forever there...)

In case the document does not contain any confidential information or is
