As requested:

When a balsa mblist is created, it is populated with the existing mailboxes.
These mailboxes are shared between all instances of the mailbox tree.
Signals then get connected to the _mailboxes_, with the _tree_ as user data!
Now, guess what happens when the tree disappears? The functions will get
called with an invalid pointer argument, causing a segfault in gtk.
The solution is to disconnect the signals on destroy. I copied the code
(first 10 lines) from repopulate into destroy. I don't yet know if that has
ill side effects, but I don't think so. If anything, it would affect all
like submenus, which is not a problem because they're short-lived and don't
display message counts anyway.

The fix will be included in my next patch.
