Comment (by munderl):

 I discovered that I was wrong assuming there is an IDR frame following the
 SPS/PPS.
 The whole stream does actually not contain any IDR but normal I slices
 only!

 This might produce the single broken frame in the beginning that is still
 existing even with the B slice removed and might also be responsible for
 baffling the decoder.
