I tried it and it does appear to be the SnowballPorterFilterFactory that
normally does the accent folding but can't here because it is not multi-term
aware. I did notice that the text_de field type that comes in the Solr 3.6
example schema handles your case fine. It uses the
GermanNormalizationFilterFactory to fold accented characters and is
multi-term aware. Any particular reason you're not using the stock text_de
field type? It also has three stemming options which might be sufficient for
your needs.
In any case, try to make your text_de field type closer to the stock
version, and try to use GermanNormalizationFilterFactory, and that may be
good enough for your situation.

I'd guess that this is because SnowballPorterFilterFactory
does not implement MultiTermAwareComponent. Not sure, though.
Yes, I think this hinders the automagically multiterm awarness to do it's
job.
Could an own analyzer chain with <analyzer type="multiterm"> help? Like
described (very, very short, too short...) here:
