Okay I did some investigation and understood the issue.

`package-load-descriptor' was misscompiled and returning always nil as
the compiler was not fully picking up the user defined types at compile
time, it worked only after the first faulty compilation (thing that made
the investigaiton a bit slower).

I'm working on a more complete fix but this requires careful testing, I
pushed now c8e527cbeee in order to have master stable again while I keep
working on the most comprehensive fix.

Best regards
