Please convert this application to use the system's crypto policy for SSL and TLS: https://fedoraproject.org/wiki/Packaging:CryptoPolicies If this program is compiled against gnutls, change the default priority string to be "@SYSTEM" or to use gnutls_set_default_priority(). If this program is compiled against openssl, and there is no default cipher list specified, you don't need to modify it. Otherwise replace the default cipher list with "PROFILE=SYSTEM". In both cases please verify that the application uses the system's crypto policies. If the package is already using the system-wide crypto policies, or it does not use SSL or TLS, no action is required, the bug can simply be closed.
libgadu in Fedora is built against gnutls and is using src/events.c:272: gnutls_set_default_priority(tmp->session); already.
