Comment 1 Albert Astals Cid 2013-07-28 22:02:56 UTC 
I guess it's a latex file that takes "a while" to generate, right? Or can you also reproduce with "very simple" latex files?
Comment 2 auxsvr 2013-08-01 17:58:47 UTC 
In order to reproduce this the PDF file must take so long to generate, that "Reloading the document..." is displayed while attempting to close okular. For small latex files the window of opportunity is too short.
Comment 3 Albert Astals Cid 2013-08-01 20:25:26 UTC 
I don't have such a big latex file, can you provide one to us to help reproduce the problem?

Large tex document
Comment 5 Albert Astals Cid 2013-08-05 22:15:35 UTC 
I'm getting

! fontspec error: "font-not-found"
! 
! The font "Minion Pro" cannot be found.
! 
! See the fontspec documentation for further information.
! 
! For immediate help type H <return>.

Do you have any clue how to install that font on Ubuntu or maybe you can use a different font?

Sorry i'm a tex noob

It is enough to copy Minion Pro and Myriad Pro (*.otf) fonts from Adobe Reader Linux distribution to /usr/share/fonts/OTF (I can send you an archive with them if you need it) then run xelatex.

Comment 8 Albert Astals Cid 2013-08-17 15:37:40 UTC 
Possible solutions, make 
    TOCModel *m_oldModel;
be a QPointer so it gets automatically nulled when it's deleted or
change parentship of m_model in toc.cpp when calling setOldModelData/clearOldModelData

Both look not nice. Comments on what you guys think its less worse?

I just updated the pdf and moved it elsewhere. Then I tried to close okular and it crashed.
