I don't remember exactly, but it has something to do with Hibernate lazy collection proxies being accessed outside of a Session, etc. The fetch type of 'eager' has been set for 'messages' collection in 'Mailbox' model, etc. You could see the exact diffs by going to GitHub (it shows you diffs visually quite nicely).
On your end, you don't have to do anything other then fetching a fresh copy of the source code from GitHub, doing 'grails upgrade', installing necessary plugins and that's it.

Sure. Feel free to clone (fork) the GitHub repo and hack away. When you have some features ready, just send me a 'pull' request, so I could incorporate the code into my repo's 'master' branch, etc. That's the beauty of git and GitHub! :-)
If you are not familiar with 'git way of working', GitHub has some nice pointers:
BTW, I just started using new GitHub's 'issues' instead of Lighthouse:
