We ran into similar problems with users registering their ssh keys on
opensolaris.org. The main problem was extra, usually trailing,
whitespace. I think we added a note to the web page warning people to
check for, and delete, extra whitespace. That seemed to reduce the
number of emails about ssh problems. (For XEmacs, we might only be able
to add a note to xemacs.org, where we point people at Bitbucket.) We
could also add a warning about copying multiple lines at once from a
terminal emulator. (I avoid copying from an emulator, precisely because
of newlines and Emacs line-wrap characters getting introduced.)

By "browsing to the file", do you mean the "Choose key" button in the
user profile page? I couldn't get that to work at all. I click on the
button and nothing happens. *shrug*

(For Steven M.) Yes. There are different encryption algorithms, and
it's important to know the difference between public and private keys.
If you're not familiar with public key cryptography, the Wikipedia
page and HowStuffWorks page both look decent. That'll give you
some general background. Then I recommend reviewing Bitbucket's SSH
Help page if you haven't already.
