Description Stan Angeloff 2012-07-19 10:27:20 UTC
When opening a .NEF file on a stock Ubuntu Precise 12.04 with libopenraw 0.0.{8,9} installed from source, Eye of Gnome exists with SIGSEGV.

I have the following set up:

1. Stock Ubuntu Precise 12.04 with the default libopenraw1 and libopenrawgnome1 installed:

$ sudo apt-get install --reinstall libopenraw1 libopenrawgnome1

2. Running the latest available kernel and GCC:

$ uname -a
Linux stan-inspiron 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

3. A test .NEF image (too big to attach, using Dropbox instead http://dl.dropbox.com/u/24705742/test.NEF)

By default, Ubuntu doesn't come with the pixbuf loader for camera raw images. These are the steps I followed to install libopenraw from source (please note 0.0.8 used to match the version installed in Ubuntu, 0.0.9 has the same behaviour):


$ cd /tmp
$ curl -O http://libopenraw.freedesktop.org/download/libopenraw-0.0.8.tar.gz
$ tar zxvf libopenraw-0.0.8.tar.gz && cd libopenraw-0.0.8
$ sudo apt-get install libboost-test-dev
$ ./configure
$ sudo cp ./gnome/.libs/libopenraw_pixbuf.so /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/
$ sudo gdk-pixbuf-query-loaders --update-cache


Using gdk-pixbuf-query-loaders I can confirm the system now has libcameraraw pixbuf loader installed.

When I attempt to load the test.NEF file I get a segmentation fault as shown in this gdb session:


$ gdb --args eog /data/Dropbox/Public/test.NEF

I am no good at writing C so I haven't attempted to address the issue. I hope this bug report contains the information you'd need.

Any Qs, please let me know and would be happy to assist.

This is a know bug in libopenraw with D300 files. I haven't managed to find the time to fix it.
Comment 2 Sebastian Pipping 2013-09-16 16:34:54 UTC
Before there's a real fix to this, maybe loading of D300 NEF images should be temporarily disabled in libopenraw?  Without checking, this could even be a security issue.
Comment 3 Hubert Figuiere 2014-04-13 14:06:35 UTC
As of today it works with libopenraw master, at least the samples I have. Maybe it got fixed in the meantime.
