The decode method depends on "data" which is referenced as a global.
Perhaps data should be passed into decode as a second argument. My
edited version:
def decode(self, data):
^^^^^^
import struct
format='4s 4s 48s 48s 64s 4s 256s 128s 128s 48s'
size=struct.calcsize(format)
#self.data=data # not needed
^ ^^^^^^^^^^^^^^
self.structid, self.version, self.qname, self.processname,
\
self.triggerdata, self.appltype, self.applid,
\
self.envdata, self.userdata, self.qmgr
\
= struct.unpack(format,data)
^^^^^ (removed self.)

I am suggesting that the data to be unpacked gets passed into the decode
method as an argument:
test.decode(data)
I changed the struct.unpack call to use the data argument.
Some additional suggestions:
size is never used. perhaps you want:
assert size = <correct size>
import struct
could be moved to the top of the script and imported once
Hopefully this helps.
