Key signature shifted

[Denis Bitouzé]

Hello,

in the following MWE:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.16.2"

music = { c c c c }

musicA = \relative c'' {
  \key c \major
  \music
  \key d \major
  \music
}

musicB = \relative c'' {
  \key g \minor
  \music
  \key c \major
  \music
}

musicAPart = \new Staff \musicA

musicBPart = \new Staff \musicB

\musicAPart

<<
  \musicAPart
  \musicBPart
>>  

\musicBPart
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

the key signature with 2 sharps in 2nd measure:

  1. line 1, is located just after the preceding bar

  2. line 3, is shifted to the right.

Is it a bug or a feature? ;)

Thanks.
