Comment 8 for bug 156679

I confirm the issue but I cannot explain it. Here is the backtrace:

I have absolutely no idea what may cause this crash. The workaround is to play at another python based activity first.
I tested on gutsy GCompris 8.3.4, the latest stable in the 8.3 branch and it does work fine.
Sadly, there are no changes I can see concerning this code. There maybe a side effect in the build process or from another
fix.

Can someone build a 8.3.4 on gutsy following the official process and check if the problem is still there.
