Looks like issue is earlier in the process.
One of the load_stream/unpack/dcraw_process is silently failing to allocate some memory, so when it comes to the dcraw_make_mem_image it is being told that width/height/etc are all 0, hence no error, but no return data.
If I can determine where it is failing I'll pass it on, otherwise - feel free to ignore me for now :)
