If this doesn't work, that would be a bug.  I've forwarded the message to
bug-lilypond, and the Bug Squad should be getting an issue created.

I hope that I'll be able to get it fixed in a day or two, but I'm really
busy today.

As a workaround, may I suggest that you define a couple of LilyPond
variables

setThreeFour = {
  \time 3/4
  \set Score.beatStructure = #'(1 1 1)
  \set Score.beamExceptions = #'()
}

setFourFour = {
  \time 4/4
  \set Score.beatStructure = #'(1 1 1 1)
  \set Score.beamExceptions = #'()
}


Then, instead of \time 4/4, use \setFourFour.

HTH,
