I reproduced your setup and I think I found it: "shared-blob-dir false" 
seems to be incompatible with ZODB 3.8, because the blob code in ZODB 
3.8 constructs blob filenames in an inflexible way.  IOW, 
BlobCacheLayout was never intended to work with ZODB 3.8.  I expect my 
test runner to confirm this within the next couple of hours, then I'll 
make it so "shared-blob-dir false" is not available with ZODB 3.8.
