QSslCertificate::fromPath() does not load certificates when given a wildcard

QSslCertificate::fromPath() does not load certificates when given a wildcard.

For instance,
QSslCertificate::fromPath("/tmp/tcert.pem", QSsl::Pem, QRegExp::FixedString);
works, but the following fails:
QSslCertificate::fromPath("/tmp/tcert.pem", QSsl::Pem, QRegExp::RegExp);
