Hmm I wonder if has anything to do with my sync setup and not with anything conboy is doing. I have previously had the tablet send the notes over rsync+ssh when I connected to my home network. Tomboy initially was fine with the notes sent via this setup but about a month ago it 'broke'. These sync'd quite a lot - every time my tablet connected to my home network. Perhaps a transfer got messed up somewhere along the way. Conboy chugged along just fine so I just used that and periodically gnote. I did not really stop and take a look at the problem notes until I read that tomboy and conboy support U1 and wanted to try it.
I just do not want to fill you new obtained thesis free time with problems that may not be conboy's fault. I'll keep an eye on it and see if I can recreate it.
