AttributeError: 'QGroupBox' object has no attribute 'startswith' when clicking on local device removal button

[Mike McCracken]

On Saucy, with control-panel trunk, clicking on the remove-local-device button occasionally raises this exception, and fails to delete the token:

2013-11-19 15:34:17,145 - ubuntuone.controlpanel.backend - WARNING - remove_device.

As I got an email the security upgrade for Ubuntu One, I tried to follow the directions on https://one.ubuntu.com/help/faq/i-received-an-email-saying-i-should-remove-and-re-add-my-account-what-does-it-mean/
I get this error message when trying to remove my device, and waiting "for 15 minutes" before trying again does not help.

I'm facing the same problem.

As of today, the same problem hits me on most recent 14.04 64-bit system

This bug affects me on an Arch machine; for a week now I haven't been able to log in; I always get AUTH_FAILED in the control panel.

ALL,
open terminal type "seahorse"

one window will get open click on "Login" and just change the password in your 'ubuntu one" account
again start ubuntu one you will see its done !!!
if not then restart whole system. it shoukd ask for your login so you can enter it again without removing your local device

Cheers!!!
