Okay, I give up. When I let my session manager close gmb, it ends up unexpectedly with the error message :
The same behaviour can be repeduced by using "xkill" to terminate gmusicbrowser. So it's not an issue of catching the right signal, and I don't know what's causing this (it might not be related to gmb at all !).
Code Select
gmusicbrowser: Fatal IO error 11 (Ressource temporairement non disponible) on X server :0.
