Description Jerome Pansanel 2015-04-24 12:24:18 UTC
When I try to load a molecule with the molecular editor, it is not displayed in the molecule window.

The bug has been observed with the Ubuntu 14.04 package and could be verified by compiling the source (v2.4.03).

Reproducible: Always

Steps to Reproduce:
1. Select Tools -> Molecular Editor
2. Click on Load Molecule and select ethane.cml
3. Select one of the CML file and click on Open

Actual Results:  
The molecule window stay empty.

Expected Results:  
The molecule should be displayed in the molecule window.

When I open Kalzium on Ubuntu 14.04 Desktop, the wrong molecular editor window comes up.  It appears to be the older version of Avogadro.  Maybe the pointer is selecting the wrong version or the wrong Avogadro is embedded somehow.

Avogadro on my Ubuntu 14.04 lists:  Application Version 1.1.1, Library Version 1.1.1, Open Babel Version 2.3.2 and Qt Version 4.8.6.   What appears to be happening is the Avogadro version that shows up from Kalzium is what it looked like back in the Ubuntu 10.04 version.   I think that this problem may also have come up with the Ubuntu 12.04 version as well.

Best of luck on nailing this bug.

The molecular editor worked properly inside Kalzium with the version that worked on Ubuntu 10.04 LTS.  I used Ubuntu 10.04 LTS until I switched over to Ubuntu 14.04 LTS.  The molecular editor on Kalzium had a revamped menu system but the molecular editor came up and only displayed a blank black screen.  I was told to try using avogadro. I was happy found that avogadro--which appears to be the molecular editor in stand-alone mode worked fine.  It also seemed an improvement.

Some time ago, I noticed that the molecular editor called by the present Kalzium appeared to fetch the older avogadro screen or its library version!  It never called the newer screen as far as I could tell.  Do you suppose that this could be the issue?  I'm not capable enough as a programmer to decipher this on my own.  I only write simple scripts in Bash and Python. Unfortunately, I don't have a version of Kalzium that ran on Ubuntu 10.04 LTS anymore.

For my Ubuntu 14.04 LTS, my Kalzium version is  2.4.01  using the KDE Development Platform 4.13.3  (Avogadro inside it doesn't give information on itself.)
My stand-alone Avogadro version is 1.1.1, library version 1.1.1, Open Babel version 2.3.2, Qt version 4.8.6.  My computer gives the following when typing the uname -a command:  Linux madmod-laptop 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:02 UTC 2015 i686 i686 i686 GNU/Linux.

The molecule editor was ported to Avogadro 2 for the upcoming Kalzium release in December (KDE Applications 16.12). With that version I cannot reproduce the bug.
