[0.4.2] Imported PGP5 keys: multiple recipients, trust values

I've encountered some weird problem when using keys imported from PGP5
and encoding messages for multiple recipients. I don't know whether
this is a known issue or has been discussed before; so I'll illustrate
the problem using an example.
Let's suppose I've imported a sec/pub key pair from PGP5, whose user ID
is "foo", and a second public key, named "bar" (both are DSS/DH
keys). Used separately, each of those keys works just fine, but if I
try to encode a message using both keys, say
$ echo test | gpg -r foo -r bar -e | gpg
GPG (as expected) prompts me to enter my secret key's ("foo") pass
phrase, and then dies with an error:
gpg: public key decryption failed: Secret key not available
gpg: decryption failed: Secret key not available
However, if I change the order of the given key ID's, so as the key
whose secret counterpart I possess is specified last:
$ echo test | gpg -r bar -r foo -e | gpg
Has anyone experienced anything similar or any suspicions as to what
this behaviour might be caused by?
On something else that's related to PGP-imported keys, too: I've
imported a DSS/DH PGP5 key which is signed by an old-style RSA key.
Even though I've signed the key (using another imported, ultimately
trusted key), GPG fails to calculate a trust value for it. May this be
due to the fact that GPG complains as follows when checking the key's
1 signature not checked due to a missing key
If so, is there a way to remove this superfluous signature?
