In the second line, it sends nextBytesPutAll: to the unbuffered stream. Which should be fine if it inherits from Stream. But ZnBufferedWriteStream does not inherit from Stream.
The fix I found is simple, but I don't understand the whole system well enough to be sure that it doesn't cause trouble elsewhere. I added the method ZnBufferedWriteStream >> nextBytesPutAll:
nextBytesPutAll: aCollection self nextPutAll: aCollection and all my problems are gone. Konrad.
