Okay.

Don't spend too much time on it, I was willing to feed a bug report if that 
was supposed to be a bug and I'll do it, but before starting a long git-
bisect, I was just asking here if this was known and related to some in memory 
cache or something like that.

I'll collect more info and open an issue on github, for now, the informations 
I have are rather weak.
