Comment 1 Albert Astals Cid 2018-04-24 22:14:07 UTC 
the backtrace is very strange.

Can you try running okular under valgrind

valgrind okular myfile.pdf

and attaching the output you get when doing the same steps?

Comment 3 Albert Astals Cid 2018-04-25 07:36:55 UTC 
Invalid write to eventfd: Bad file descriptor
Code should not be reached at pulsecore/fdsem.c:199, function pa_fdsem_post(). Aborting.

This tells me there's something wrong going with your pulseaudio. Which version are you using? Maybe you should try opening a pulseaudio bug?
Comment 4 Patrick Silva 2018-04-25 12:41:27 UTC 
My neon dev unstable runs pulseaudio 8.0.

I can not reproduce the crash on Arch Linux running pulseaudio 11.1 and okular 1.4.0

I just noticed something: on neon okular shown a message when I changed to presentation mode talking about ways to exit (ESC key and a button). After I check "do not show again" I can not reproduce the crash anymore.
Okular does not show such message on Arch Linux.

I'm 99.99999% sure it does, it's probably that you already pressed "don't show again" before, no?

Maybe. However I do not remember it.

Comment 10 Sebastian 2018-09-16 14:37:32 UTC 
I can also reproduce this bug

Kubuntu 18.04
Okular 1.3.3
Pulsaudio 11.1

Is there a big ID for Pulsaudio?
Comment 11 Tobias Deiminger 2018-09-16 21:50:13 UTC 
I can reproduce the bug and will have a look into it. Someone closed libpulses eventfd(2), while libpulse continues to write to it. A write to the already closed fd in pa_fdsem_post then triggers assertion. I modified pulseaudio to get a bit more debug info:

$ strace -e close ./okular 2>&1 
[...]
close(19)                               = 0
close(15)                               = 0     # who is doing that? and why?
close(15)                               = 0
close(15)                               = 0
close(19)                               = 0
close(21)                               = 0
[...]
Invalid write to eventfd: fd=15, r=-1, errno=9  # pa_fdsem_post tried writing fd 15, too late, already closed

I think next thing to check is where the close happened. Could be okular, Qt, or pulseaudio itself.
Comment 12 Tobias Deiminger 2018-09-17 07:10:02 UTC 
Ok, got it. It's this place in PresentationWidget::inhibitPowerManagement
  m_sleepInhibitCookie = reply.value().fileDescriptor();

We must not store QDBusUnixFileDescriptor::fileDescriptor, but clone it before. From http://doc.qt.io/qt-5/qdbusunixfiledescriptor.html#fileDescriptor
"It is ok to use it while this object is valid, but if one wants to store it for longer use, the file descriptor should be cloned using the Unix dup(2), dup2(2) or dup3(2) functions."

Changing the code to
  m_sleepInhibitCookie = dup( reply.value().fileDescriptor() );
avoids crashing.

Let me gather a bit more context to see if it's really that simple, then I'll send a patch at Phabricator. Maybe one can try and confirm the above code change in the meantime?
Comment 13 Albert Astals Cid 2018-09-19 18:07:15 UTC 
Tobias fixed this, he forgot to use the correct syntax so it did not autoclose.
