version 2.18.2 - incorrect bar numbers with full measure rests

[Eby Mani]

version 2.18.2

With 4/2 time, Bar numbers are incorrectly printed when using full measure 
rests.

Even printing bar numbers for each measure is numbered incorrectly(attached 
sample).
\context {\Score \override BarNumber.break-visibility = #all-visible }

Is there a way to print them properly other than manually adding them ?.

Thanks,
eby
