Bug Description

When using an ampersand character in the title of a note, synchronization between Tomboy and Ubuntu One stops working or the title is messing up. There are two options:

1) Create a note with the title "Peter & Paul" via the Ubuntu One web interface. Then try to sync Tomboy. Tomboy fails to sync without giving details. I'll attach the exception.
After that rename the note to "Peter and Paul" again using the web interface. Then try to sync Tomboy. It works as expected.

2) Create a note with the title "Peter & Paul" via Tomboy. Then try to sync Tomboy. It will work, but the note title on Ubuntu One is messed up. It now reads "Peter & Paul". I'll attach screenshots.

This bug might be related to #484683, #482372, #479417 and #484142

I'm guessing that this is caused by the XML<->HTML conversion code, since this bug isn't present in Snowy. So, once U1 stops converting every note, it should only impact notes edited in U1's online editor until the bug is fixed.

I've just submitted a branch that changes all notes to be stored in XML (all notes that you change, as an upgrade path, so notes already in HTML that are not changed will still be in HTML, but as soon as you edit them, they are stored in XML). As for the & in the title, fixing it now

Awesome, sounds like a good solution!
