This now works correctly in 2.11.2.

As an example, the measures in the first score in the example below
render with exactly the same lengths as the measures in the second
score. Prior to 2.11.2, the first measure in the first score rendered
too short.

%%% BEGIN EXAMPLE 1 %%%

\version "2.11.1"

\layout {
 ragged-right = ##t
}

\score {
\new Staff \with {
   \remove Separating_line_group_engraver
} {
    \relative c' {
        \override Score.SpacingSpanner #'uniform-stretching = ##t
        \set Score.proportionalNotationDuration = #(ly:make-moment 8 50)
         \override Score.PaperColumn #'used = ##t
        \time 4/4 r1 % bug now fixed; measure length is correct
         \time 3/8 r4.
        \time 5/4 r1 r4
        \time 5/16 r4 r16
        \time 5/8 s2 s8
        \time 5/8 r2 r8
    }
}
}

\score {
\new Staff \with {
   \remove Separating_line_group_engraver
} {
    \relative c' {
        \override Score.SpacingSpanner #'uniform-stretching = ##t
        \set Score.proportionalNotationDuration = #(ly:make-moment 8 50)
         \override Score.PaperColumn #'used = ##t
        \time 4/4 r4 r4 r4 r4
         \time 3/8 r4.
        \time 5/4 r1 r4
        \time 5/16 r4 r16
        \time 5/8 s2 s8
        \time 5/8 r2 r8
    }
}
}

%%% END EXAMPLE 1 %%%

Orm, are you now able to get the look and behavior you want from the
proportional notation parameters, under 2.11.2?
