Default generateBoundaryLayers failed - how to split edges

tkr is on a distinguished road
I would like to create boundary layers (only!) on a certain patch of a complex geometry but their generation during the meshing procedure (cartesianMesh, OF v2006) doesn't work. The syntax I used is
Code:
boundaryLayers
{
    nLayers 0;       
    untangleLayers 0;    
   
    patchBoundaryLayers
    {
        "boundarylayer.*" //patch name
        {
            allowDiscontinuity 1; 
            nLayers 5;
            thicknessRatio 1.2;
        }
    } 
}
The log-output gives the information that new cells were created:
Code:
Detecting layers
Analysing mesh for bnd layer existence
Generating hair edges
Finished with bnd layer detection
Finished refining boundary - layer faces 
Number of newly generated cells 107912
Finished generating new cells
But the added boundary cells aren't visible in Paraview. After, I tried to produce the mesh first and add the boundary layers using the generateBoundaryLayers. Unfortunately, the utility crashes with a fatal error
Code:
Splits in direction (1 5)
Here 
Dir0 -1
dir0Edges (-1 -1)
Dir1 -1
dir1Edges (-1 -1)

--> FOAM FATAL ERROR: 
Cannot find split edges for a face
How can I split edges for cfMesh or is there any way to work on that?
