Confirmed.  The issue isn't in an m-file, but in the C++ code for patch objects which apparently does not have a test for this.

Octave will run this example, and generate a plot:

np = 30;
p = rand(np, 3);
h = convhull(p);
nfaces = size(h, 1)
val = rand(nfaces + 1, 1);
patch('vertices', p, 'faces', h, 'facevertexcdata', val, 'facecolor', 'flat');

where as matlab reports

Warning: Error creating or updating Patch
 Error in value of property  FaceVertexCData
 Number of colors must equal number of vertices or faces
