The error message is a bit misleading here (I'll fix it soon); the reason why 
igraph is complaining is because it cannot find a suitable image viewer 
application on your machine. On Linux, this is done by looking for a set of 
widely used image viewers:

- eog
- gthumb
- gqview
- kuickshow
- xnview
- display
- gpicview
- gwenview
- qiv
- gimv

You should either install one of these, or specify the full path of your image 
viewer in a file named .igraphrc in your home directory. The file should look 
like this:

[apps]
image_viewer=/usr/bin/your-image-viewer

All the best,
Tamas
