Decompression with zlib

I'm trying to do compression/decompression of stuff with zlib, and I
just don't get it...
Here is an example. I assume that dec should be "a", but it isn't. dec
turns out to be an empty string, and I don't understand why...
compressor = zlib.compressobj(6) # level
decompressor = zlib.decompressobj() # wbits
cmpr = compressor.compress("a")
print "compressed", len(cmpr)
dec = decompressor.decompress(cmpr)
print "decompressed", len(dec)
# unconsumed tail and unused data
print "decompressor.unconsumed_tail", decompressor.unconsumed_tail
##print "decompressor.unused_data", decompressor.unused_data
dec += decompressor.flush()
print "after flushing", len(dec)
Any help is appreciated.
