It appears that a newer version of libsoup or gnutls set the default client required prime number minimum to be higher then what the gtalk/gmail servers are configured to give out. This causes the connection to fail with a GNUTLS_E_DH_PRIME_UNACCEPTABLE error. net-voip/telepathy-gabble should specify to libsoup or gnutls that it requires a lower prime number then the default. bz #456250 gets around the problem by switch to OpenSSL where telepathy-gabble either specifies this or the default in OpenSSL is lower. Reproducible: Always Steps to Reproduce: 1. Update to the latest on ~amd64(sorry don't recall which version this happened on) 2.
