Comment 1 Albert Astals Cid 2012-10-08 21:20:56 UTC 
Did you compile against your system kdelibs? did you set your KDEDIRS envvar?

It can fail in some extreme cases

(In reply to comment #1)
> Did you compile against your system kdelibs? did you set your KDEDIRS envvar?
I compiled the sources using the following command:
cmake ../ -DCMAKE_INSTALL_PREFIX=~/okular-install -DCMAKE_BUILD_TYPE="Debug" -DFREETYPE_INCLUDE_DIR=/usr/include/freetype2/freetype
Comment 5 Albert Astals Cid 2012-10-08 22:12:34 UTC 
which doesn't answer the question if you set your kdedirs envvar, or probably means you didn't?

Read the last bit of http://okular.kde.org/download.php

Pull from git and this crash will go away (you'll still get a non working okular without the KDEDIRS thing though)
Comment 6 Tobias 2012-10-08 22:20:42 UTC 
I run `export KDEDIRS=~/okular-install/bin/okular:$(kde4-config --prefix); kbuildsycoca4` but it does hinder Okular from crashing.
Comment 7 Albert Astals Cid 2012-10-08 22:40:38 UTC 
If it does hinder okular from crashing all is good, no? Or you mean it still crashes?
Comment 8 Tobias 2012-10-08 22:47:45 UTC 
It does not hinder Okular from crashing. Sorry for the typo.
Comment 9 Albert Astals Cid 2012-10-08 22:52:10 UTC 
the KDEDIRS is wrong, does ~/okular-install/bin/okular seem something that is worth of being named "KDEDIRS"?

KDEDIRS should be ~/okular-install that is where you told cmake to install okular, also not sure if the ~ will work so give it a manual substitution just in case
Comment 10 Tobias 2012-10-08 22:56:52 UTC 
Finally `export KDEDIRS=~/okular-install:$(kde4-config --prefix); kbuildsycoca4` works. Sorry, but the path was not totally understandable for me from the website. Thank you!
