A more minimal example would be nice -- say, two notes in a chord.

If you look closely, and draw a box around each symbol (accidental, 
accidental+parenthesis), and imagine 0.2 staff-line-widths of padding 
around each box, you will see that the boxes+padding _are_ colliding. 
Improving collision detection is an ongoing task with lilypond.
