Upgrading production systems can be expensive - hence the value of paid 
long term support contracts.  I don't think he is asking to fix it - 
just to confirm that it is an LVM bug, which could make upgrading more 
attractive, or make the workaround (of ensuring snapshot size <= source 
size) acceptable.
