> "hydrogen" is not distributable because its license "GPL-2" conflicts with license "OpenSSLException" of dependency "qt5-qtbase"

Does this make sense or is there an error in the script? Why would GPL-2 or anything conflict with OpenSSLException? It's just an exception. It lifts some restrictions imposed by the GPL. It shouldn't be imposing additional restrictions itself, should it?
