Any guess at what would cause this?

Feb 7 21:20:53 server dovecot: imap(user): Panic: file mailbox-list-fs-iter.c: line 447 (fs_list_get_roots): assertion failed: (full_fs_access) LIST command that had invalid parameters that somehow got through the first validity check. What namespace config do you have?

namespace { alias_for = hidden = yes list = no location = prefix = / separator = / }

This one causes these crashes. Fixed in v2.2 now: http://hg.dovecot.org/dovecot-2.2/rev/fb367a977077

Thanks for diagnosing this. I'll probably remove this namespace or limp along until 2.2 becomes the latest stable release.

I added this namespace alias in an abundance of caution: this was to prevent users from trying to peruse the entire file space e.g. /etc. A poor man's chroot. I didn't test this thoroughly to see if it actually did what it was supposed to.
