Just tried to do this (2.12.2) and I'm getting 6/8 beaming in a 3/4
passage :-( Am I doing anything stupid?

voiceTimeSig = {
        \override Staff.TimeSignature #'style = #'()
        \key f \major
        \time 3/4
#(revert-auto-beam-setting '(end * * 3 4) 3 4)
\set beatGrouping = #'(1 1 1)
        s2.*8  % mark 1
        s2.*6  % mark 2
        \time 2/4 s2 \time 4/4 s1


Cheers,
