I think this is a bug, but I wanted to run it past the users' group first.
The heart of the problem is that the function articulate is not producing the correct MIDI output with grace notes in certain situations. The symptom is that a bar check fails.
Below is a MWE. I know it doesn't look very minimal, but it's about as small as I could get and still produce the problem.
%{
Problems with the articulate function with grace notes, barchecks and
explicit contexts. On line 19, the barcheck will fail.
Comment out any one of the lines with "this line" at the end and the
problem disappears.

\version "2.19.82"
\language "english"
rightHand = \relative {
<<
\context Voice = "1" { \voiceOne s4 ds''2.( }
\context Voice = "2" { \voiceTwo s4 e,2. } % this line
>> |
\context Voice = "1" { \voiceOne \grace { ds'8) } } % this line
\oneVoice ds4 e8. ds16 cs4 ds4 | % <-- fails here
}
% this is just for diagnostics

\new Staff \rightHand

\score {
\articulate { % this line and its closing brace

Here is more context if it helps:
