Error: Could not load keystore/truststore

I have the same problem here up to version 5.0 (Nigthly). The Certificate and Password can be load and used for requests via "Preferences/SSL Settings". But if I take the same settings in the WS-Security settings, to use it with different environments, the error described from parwezwahid appears.

Some more Message from the console:

15:47:32,071 ERROR [SoapUI] An error occurred [failed to extract any certificates or private keys - maybe bad password?], see error log for details
15:47:37,078 WARN  [KeyMaterialWssCrypto] Using fallback method to load keystore/truststore due to:
Invalid keystore format
Please report bug!
PKCS12 detection failed to realize this was PKCS12!
------ ASN.1 PKCS Structure ------
oid1:    HIDE
salt:   HIDE
ic:      HIDE
bigPayload-length:   HIDE
All oids:
HIDE

and after press enter in the Password field of "WS-Security/Keystores" following message appear.

Thx a lot!
