"Value could not be retrieved" keeps appearing ont the control panel

Hi David,

Thanks for your report. Yes, we need to improve the error messages but is not easy, since we're getting exceptions back from the backend and we need to show a fixed, translatable error for the end users. Right now we can't define strings for all the possible errors from syncdaemon, so we are showing predefined errors.

Anyways, I agree we should try to improve this somehow.

Confirmed on natty beta1, the device tab display this error in red which is not a real user friendly way to say I've no device configured ;-)

Sebastien's report was isolated in bug #745790, since is not this exact same issue.

This bug was fixed in the package ubuntuone-control-panel - 0.9.5-0ubuntu1

---------------
ubuntuone-control-panel (0.9.5-0ubuntu1) natty; urgency=low

  * New upstream release:

    [ <email address hidden> ]
      - Now that we set the launcher urgency from ubuntuone-client, the control
      panel needs to remove it when its window receives focus (LP: #747677).
      - changed default value for switch_to to empty string, and now don't call
      switch_to method when the value is empty string (or anything else falsy)
      (LP: #752943).
      - Added proper defaults to the command line arguments (LP: #746489).
      - Fixed issue where closing the panel resulted in a runtime error
      (LP: #745987).
      - This adds a method to the dbus service that allows switching between
      panels, and/or drawing attention to the control panel (LP: #742008).
      - Removed the shortcut group that causes two Ubuntu One entries to appear
      in the messaging menu when syncdaemon is not running (LP: #721525).
    [ Natalia B. Bidart <email address hidden> ]
      - If servers reply with a 401, clear credentials and ask user to
      authenticate (LP: #726612).
      - Moving style_check down so the exit code from u1trial is not hidden by
      && operator.
      - Unify disable/enable file sync functionality among Services tab and
      global file sync status (LP: #729301).
      - Cloud Folders tab is now disabled when the file sync service is
      (LP: #747482).
      - Improving legend for plugin installation to ease translations
      (LP: #746374).
      - Added volumes.ui to the translation list (LP: #746370).
      - Small improvement to show something else besides the generic "Value can
      not be retrieved." error (LP: #722485).
      - Made the backend robust against possible None values (or any non
      basestring instance) sent from the API server (LP: #745790).
      - Decoupled device list retrieved from the web from the local settings
      retrieved from syncdaemon (LP: #720704).
      - Stop the control panel backend once the UI is done
      (LP: #704434).
      - After initial computer adding, syncdameon is asked to connect
      (LP: #715873).
