Unable to change bad user/pass for export to picasaweb

Binary package hint: f-spot

I apparently entered my user name and password wrong in the export dialog box for picasaweb (do we have to end the user name with @gmail.com?).

Now I am not able to edit it. It tries to connect using the old user/pass. This generates a 404 exception.

Output from console (using --debug):
GoogleAccount.Connect()
Can not connect to Picasa. Bad username ? password ? network connection ?

Output shown in Dialog box:
