Error with prosody-trunk

[kriztan]

I don't know if this is still active here, but I want you to know, that there is an error on registering an account with prosody-trunk.

.../lib/prosody/modules/mod_saslauth.lua:55: attempt to call method 'reset_stream' (a nil value)

The account is created, but login is not possible. There is no error nor a hint shown in the client (what should be).
