G'Day,

I'm sorry I haven't been able to get back to you.  The issue is the same
for all of these accounts.  We simply have a password encoded in a
format that we do not correctly parse.  The 00 20 stuff is literally
some unicode space (ie the spacebar, yes!) padding that is in this
structure.  

I need to get both and encrypted copy of the data and some time to work
over it, so we can correct this issue in our IDL.
