So in the bug report, the reporter says:

openssl pkcs12 -in CertificatoASI.p12 -info -noout

gives me:

Enter Import Password:
MAC Iteration 2048
MAC verified OK
PKCS7 Encrypted data: pbeWithSHA1And40BitRC2-CBC, Iteration 2048
Certificate bag
Certificate bag
PKCS7 Data
Shrouded Keybag: pbeWithSHA1And3-KeyTripleDES-CBC, Iteration 2048

Does that mean we need both RC2-40-CBC and 3DES-CBC enabled?  Or should
this guy just re-encrypt his key?
