As the filtered collective path simply calls through the filter pipeline by way of the H5Z_pipeline() function, it would seem that either the filter pipeline itself is not handling this case correctly, or this is somewhat unexpected behavior for the pipeline to deal with.
Either way, I think a pull request/diff file would be very useful for going over this. If you're able to generate a diff between what you have now and the current develop branch/H5Z-blosc code and put it here that would be useful. I don't think that there should be too much in the way of logistics for getting this code in, we just want to make sure that we approach the solution in the right way without breaking something else.
