Yeah, Osmosis is written to be a library and has a command line bolted 
onto the front of it.  I try to create meaningful error messages but it 
does mean that you have to read through a stack trace to find them 
sometimes.

Well, in this case you'll have to be a programmer to debug it.  
Something about the plugin appears to be broken.  Perhaps it was 
compiled against an older version of osmosis?  Not sure, I don't have 
any experience debugging plugins yet.  Dave is going to have to help you 
with this one.
