Tomboy freezes during sync

[Andreas Jonsson]

I don't know what's wrong with my system but I have had all sorts of trouble with Tomboy lately, including these two bugs

https://bugs.launchpad.net/ubuntu/+source/tomboy/+bug/890837
https://bugs.launchpad.net/ubuntu/+source/tomboy/+bug/891699

and now the application also freezes during sync with the following error output:
