In the meantime, I was able to debug and found the issue : basically there is key 'Type' somewhere in the treee but the key is not a 'name' as expected but a string.
I browsed a bit the spec (PDF) and it does seem to suggest Type should always be a "name". However, other tools seem to not care about that and linearize the file (acrobat pro, pdftron). No preflight errors either from acrobat.
