Hi !

I feel not able to take decision about the proper way right now.
So as a step forward I wrote a test to capture the behavior expected.
Please have a look at it as it's the starting point for me.
Next, I can implement the error handler, making the previous test to 
pass.
As the test checks the behaviour, it will let enough space to change 
implementation later without invalitating the test.

Cheers,
Jérémy
