This is a limitation of the audio resampling filter that is being used in your case; it refuses to accept parameters outside a certain range (though IIRC things worked fine when I once tested just removing that limit). The simplest workaround is to use "-af scaletempo". The main effect of this is to use a pitch-preserving filter for audio speedup instead of the default resampling; this filter happens not to share the same limit.
