The duplicate status is wrong... who knows... because the person having posted bug #553759 didn't make it public, so I can't check!

A clue to debug this problem.

It seems to be a keyring problem (and probably not Ubuntu-one)

Previouly (Karmic) the default keyring was named: login.keyring

Now the default keyring is name, on my French system:

par_défaut.keyring

Note the "é" in the file name. The result of that seems to be that keyring is not found, and every time you try you create a new keyring like

par_défaut1.keyring
par_défaut2.keyring

I suspect a bad coding in respect to UTF-8 filename (American tend to forget there is UTF-8) in some of the keyring programs.

Ubuntu-One tries to use the keyring, and so, due to the bug in the underlying keyring access layer for UTF-8 names, fails to do so and crashes.

I have changed bug #553759 to public as the automatic retracer has set it as the "master" bug report & there is no private/ sensitive information contained within that bug report.
Comparing the traceback of this bug report & the one contained in bug 553759, it appears that the duplicate status is correct.
