slicing assembler not working with layered renders

Hi.

I’m trying to run a Maya 2011 MR-fs job with render layers and slices in Muster 6.1.1.

When Muster tries to run the assembler it seems it is looking at the wrong directory.

here is the error:
Assembler chunk 5 belonging to job StillsTest3(409) returned error: Cannot load slice file …project_files3dmayaimagesMuster_sf_409_1.iff.210:Error opening source file!

the actual images live in a sub directories named after the render layer name, ie:

…project_files3dmayaimages***beauty***Muster_sf_409_1.iff.210

Is there some way to make the assembler play nice with render layers?

thanks!
