cannot end slur

[Jonathan Wilkes]

Hello,
     I'm having trouble entering the following fragment of music:

\version "2.12.2"

\relative c'' {
        \time 3/4
        \partial 32 cis32~( |
        cis4~ cis8~ \acciaccatura e' f~ f4 |
        f16 e \times 2/3 { f des a } \times 2/3 { e d c } aes32 g'16.) ees32 b 
g d e gis c e |
}

The slur goes to the first high f, then stops, and I get a warning: 
cannot end slur.

I've tried overriding various Slur properties, but nothing seems to 
get the slur to extend all the way to the g.

If anyone has any advice or reference links, it would be greatly 
appreciated!

Thanks,
Jonathan
