 Time to time g.gui.animation crashes the the whole user graphical session.
 The error is appearing randomly and I'm not able to reproduce it now
 although I got it yesterday and few months ago, too.

 I got the error with different data and on two different computers (on
 Fujitsu laptop another Dell desktop) both running Ubuntu 14.04 with Unity
 (which uses Compiz). I think that few months ago I got it also with Ubuntu
 12.04.

 The results seems to be different. Once the session was frozen but the
 computer was running. Another time the graphical session was ended and
 login screen appeared.

 I got the error when I had two animations in the animation tool but I'm
 not sure if this is really the cause. I'm also not sure if the problem is
 in 2D rendering, 3D rendering or wxPython. For example, it seemed to me
 that it is related to `m.nviz.image` but one 3D animation was rendered
 successfully and adding second animation which was 2D caused the crash.

 Here are the last error messages are (obtained by redirecting to a file).
 Honestly, I'm not sure if I used only `DEBUG=5` or also `WX_DEBUG=5`. This
 is few months old when I was able to repeated more than once. I'm not able
 to reproduce it now, although I got it.

 I wanted to collect more information before reporting but now I got it on
 different machine and I was not able to get more information. First I also
 thought that it is a local hardware problem but now I got it with
 different machine, although both are running the same system, Ubuntu
 14.04.
