It doesn't even work correclty when the slurs are \omit-ted:

%%%

\relative{
  \key a \major
  \omit Slur
  cis'''16 -3 [ \( ( b -2 ) b ( a -1 ) \) a8 \strich ]
}

\relative{
  \key a \major
  cis'''16 -3 [ \( b -2 b a -1 \) a8 \strich ]
}
%%%

In the second example the phrasing slur correctly avoids the fingerings 
while in the first one it prints right through them.

I thought this might happen when the starting points of slur and 
phrasing slur coincide but the collision handling of the phrasing slur 
seems disabled when there is a slur *at any time*:

%%%

\relative{
  \key a \major
  cis'''16 -3 [ \( b -2 ( b )a -1 \) a8 \strich ]
}

%%%

If it is true that collision handling freaks out when slurs and phrasing 
slurs exist at the same time it would be explainable that the end points 
of both fall into one.
