Arpeggios and fingering don't play well together. I have a music 
function that I include in anything containing fingering and arpeggios 
to fix the problem. The value you need pass into the function will 
change depending on whether the chord contains accidentals etc:

\version "2.13.43"
\include "english.ly"

#(set-global-staff-size 24)

arpfinger = #(define-music-function (parser location pad) (number?) #{
    \once \override Staff.Arpeggio #'direction = #RIGHT
    \once \override Staff.Arpeggio #'padding = #$pad
#})

melody = \relative c {
    \set fingeringOrientations = #'(left)
    \set Staff.connectArpeggios = ##t
    \stemUp \arpfinger #-4 <g''-4 e>2\arpeggio f4 e \break
}
bass = \relative c {
    \set fingeringOrientations = #'(left)
<g' e>2\arpeggio d4 c \break
}
\score {
<<
        \new Staff \with {
            \consists "Span_arpeggio_engraver"
        } <<
            \clef "treble_8"
            \context Voice = one \melody
            \context Voice = two \bass

}

There are one other simple music function I use with arpeggios, which is 
sometimes needed when Lilypond positions the arpeggio too close to the 
preceding barline or note:

arpspace = #(define-music-function (parser location extent) (pair?) #{
    \once \override Staff.Arpeggio #'X-extent = #$extent
#})
