buffy doesn't let me set custom Maildirs

[Sarah Sharp]

Binary package hint: buffy

I recently upgraded from Ubuntu 10.04 to 10.10, and now Buffy doesn't work.

Buffy (version 1.2.1) does not let me set custom mail directories. I remove the default directories (/home/sarah/Mail, /home/sarah/Maildir, /home/sarah/mail, and /var/mail/sarah) and then try to add /home/sarah/Maildir.fetchmail and /home/sarah/Maildir.intel. Those directories show up in the "Folder locations" in the preferences box, but when I close that box, no folders show up in the view. Pressing update doesn't help. When I open the preferences again, I see the default folders, without my custom folders.

Here's the output from running `buffy --debug` with the actions I described:
sarah@xanatos:~$ buffy --debug

I have a .buffy file in my homedir, and buffy should be able to use that, unless the format of the file has changed? I have tried moving that file to .buffy.old, re-running buffy, and re-adding the custom folders. It didn't help.
