Dropbox library (LC 9) - does dropboxGetCurrentAccount work?

[Mike Kerner]

What was working for me was getAccount not getCurrentAccount.  If I use
LC's library with getCurrentAccount, I get the same error.
I have found the bug in LC's library, and I patched it to get it to work,
but I want to understand more of why, and also to make sure I'm not going
to break something else before I issue a pull request.
