Just found this with hw_who(): the returned array skipped some attributes and printed what looked like
a debugging string when called. Basic upshot was that the array returned didn't have all of the actual
data returned from the Hyperwave server, and all values were associated with the wrong keys (except
for 'self').

This patch seems to fix it for me:
