Further analysis suggests why there's a remote problem now in the first place:
http://www.omgubuntu.co.uk/2013/02/ubuntu-one-announce-tomboy-note-sync- to-stop-working-late-february It seems that Ubuntu One no longer actually supports note synchronisation. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to tomboy in Ubuntu. https://bugs.launchpad.net/bugs/1161687 Title: failed to synchronise; no reasons given under Details because error is not note-specific Status in “tomboy” package in Ubuntu: New Bug description: My notes are failing to synchronise. No configuration changes within Tomboy have occurred since the last successful synchronisation--only system updates have been applied. When the Details section of the Synchronisation Failed window is expanded, an empty list is shown with columns "Note Title" and "Status." Running Tomboy from a terminal indicates that the problem is remote: [DEBUG 12:03:45.153] SyncThread using SyncServiceAddin: Tomboy Web [DEBUG 12:03:45.164] Building web request for URL: https://one.ubuntu.com/notes/api/1.0/ (Tomboy:4761): Gdk-CRITICAL **: IA__gdk_error_trap_pop: assertion `gdk_error_traps != NULL' failed [ERROR 12:04:00.418] Caught exception.

However, perhaps another mechanism should exist to show synchronisation errors when those errors are not note-specific.
