Rene, Thank you for a very clear and useful bug report. I understand the problem, which almost certainly is not a linux-only problem. It will be fixed in the next release. I will make a post to the mailing list when I have checked a fix into github so that you can update your machine. Thanks, B On 11/18/2013 04:13 PM, René Genz wrote:

Hi Bruce, hi Matt,

the other day a colleague encountered a problem.

He measured a ZnO standard. I have the ZnO.fpj project file and can share the data. It is about 1.2 MB in size though. Shall I upload it to a public file hoster or sent it to your email account?

At first I thought this is a problem with my installation steps on Fedora 18 x86_64, but I could reproduce the problem with Ubuntu 12.04 i686. The line numbers match, so I will post only the output from dartemis on Ubuntu. Note: this file was created with the Windows version of Demeter on Windows 7 Enterprise 32bit (running on Fedora 18 x86_64 as VirtualBox 4.2.18 virtual machine). Demeter crashes in the Windows version as well using the steps below.

steps to reproduce: * start dartemis from a terminal

* open project file in dartemis through 'Artemis [EXAFS data analysis]' window: File -- open project

* in the 'Artemis [Plot]' window click on [R] button

* in 'Artemis [Data] ZnO' window click on the bull's eye sign to the right of rmax window

* wait about 10 seconds; dartemis will crash with the below error message

The installation steps on Ubuntu 12.04 i686 were:

sudo apt-get install -y openssl-server # for my own pleasure

sudo apt-get install -y gcc gfortran libx11-dev libncurses5 libncurses5-dev libpng3 libpng3-dev libgif4 libwxgtk2.8-dev git build-essential gnuplot perl

cd git clone https://github.com/newville/ifeffit.git cd ifeffit sudo ./PGPLOT_install ./configure make sudo make install

cd git clone git://github.com/bruceravel/demeter.git cd demeter

sudo apt-get install -y liblocal-lib-perl sudo apt-get install -y libnet-ssleay-perl sudo apt-get install -y libssl-devl # due to 'SSLeay.xs:153:25: fatal error: openssl/err.h: No such file or directory' at Net::SSLeay sudo apt-get install -y libsoap-lite-perl # automatic installation fails due to missing/not installable dependencies, hence using package from repo

sudo cpan o conf build_requires_install_policy yes o conf prerequisites_policy follow o conf commit

perl ./Build.PL sudo ./Build installdeps

perl ./Build.PL sudo ./Build installdeps

perl Build.PL ./Build ./Build test sudo ./Build install

If I should test something, let me know, please.

Thanks a lot for your help :)
