So the intermediate CA* is signed using an MD4 digest - which is weird
considering MD4 has been broken (first collisions published in 1995) and the
certificate is pretty recent (April 18th, 2011). It even use a 2048bit keypair,
that's far stronger than, even if not broken, MD4 would allow anyway.

* FWIW even the root certificate is using MD4...

968dd21d5a6c9bd6d8e2b401e19141d1bd654a7a (master) fix the issue - it's a
configuration fix so MD4 can be found (and used) automagically.

I'm now closing the bug, hopefully you won't have any more trouble (otherwise
you know the drill ;-)

A huge thank you for tracking/reporting all those failures!
