Groups: can't access notebook in My Channels

I was trying to change permissions on one of my notebooks in My Channels and it crashed to the message below. I can't access the notebook in Groups anymore as it just shows this stack trace, but I can access it from Escape just fine.

I was trying to set permissions so that only I could post to the notebook, and allow readers to comment. At the time I was also attempting to join the notebook channel from a moon, to see if I could share my notebook entries publicly by copying the link in the post.
