AisleRiot: what exactly is wrong with Block Ten?

[Zachary Keene <zjkeene bellsouth net>]

  I noticed it's been described as buggy and decided I'd take a look at 
it, but after playing several games without incident and searching the 
archives of this list, Bugzilla, Google, various logs in the CVS, etc. I 
haven't been able to determine what exactly the bugs are. Did they get 
fixed along the way without anyone noticing, or am I just missing 
something obvious?
