I switched the permalinks to numeric ones and now all old threads are
accessible.

The problem is that bbPress used to only rely on the built-in
strtolower() function, which doesn't work with UTF-8 encoded strings.
This way old slugs contained upper-case characters. Now, bbPress uses
mb_strtolower() whenever possible and this causes a mismatch between
the expected value and the value in the database.

On WordPress.com I had converted a lot of the slugs, but for the
forums numerical slugs are O.K., I think.
