g.gui.animation causes fatal IO error 11 (Resource temporarily unavailable) on X server

[wenzeslaus]

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.
