I have this same issue, too. Tomboy was doing fine when I was using the 11.10 Alpha, but I've just installed the Beta 1 and now it won't sync (nor can I press the 'save' button after authorizing) as in the previous user. I ran the 'tomboy --debug' as someone suggested elsewhere and this is what I got: $ tomboy --debug ** Running Mono with --debug ** [DEBUG 22:40:59.440] NoteManager created with note path "/home/emichelle/.local/share/tomboy".
