The problem is that without the slightest idea of where it comes from it's
difficult to make a test case. The code is public though, so I have a "large

But I'm ok to investigate on my own, if you can give me some hints... Maybe
I can switch to another serialization implementation, if I remember well
that's something possible, no?
