Spacing issue with accidental

[Stefan Waler]

Hi,

I've a spacing issue in a two-voice piece of music where the accidentals 
are printed far before the notes without any obvious reason.

I attach a sample script, please note the accidentials for 'ces' in the 
second and for 'fes' in the forth bar. I tried to simplify the score 
very much, but it seems as lilypond continues to calculate wrong spaces 
for every further accidental of this voice!

Any hints??

Thanks!

Stefan
