The top of the AUTHORS files in gpgme contains: Bug reports: https://bugs.gnupg.org . The site bugs.gnupg.org has invalid certificate.
The procedere to be entitled to report just this, is very cumbersome. I first have to register at https://dev.gnupg.org , then I have to wait for approval. In order not to forget why I need an account, I have to create a privite notice and once the account is approved, I have to read the notice. This process essentially leads to bugs not being reported.
