Bug description:
  On Cosmic Cuttlefish, gnome-music crashes on startup. This issue has
  been reported on Fedora already:
  https://bugzilla.redhat.com/show_bug.cgi?id=1635152

  Additionally, the root cause appears to be an issue in GnuTLS:
  https://bugzilla.redhat.com/show_bug.cgi?id=1634736

  Applying the patch listed there and rebuilding GnuTLS fixes the crash.

  It is likely that this issue will affect any package using libsoup
  and/or libgnutls30.

  The patch, for future reference:
