After upgrading libfreerdp2-2, authentication failures (mistyped password) started causing segfaults: May 11 11:41:29 jtriplet-mobl2 vinagre.desktop[9277]: [11:41:29:080] [9277:9277] [ERROR][com.freerdp.core] - freerdp_set_last_error ERRCONNECT_LOGON_FAILURE [0x00020014] May 11 11:41:29 jtriplet-mobl2 vinagre.desktop[9277]: [11:41:29:080] [9277:9277] [ERROR][com.freerdp.core.rdp] - rdp_recv_callback: CONNECTION_STATE_NLA - nla_recv_pdu() fail May 11 11:41:29 jtriplet-mobl2 vinagre.desktop[9277]: [11:41:29:080] [9277:9277] [ERROR][com.freerdp.core.transport] - transport_check_fds: transport->ReceiveCallback() - -1 May 11 11:41:29 jtriplet-mobl2 kernel: vinagre[9277]: segfault at 9 ip 00007fbc84bf6ab0 sp 00007ffc05377a40 error 4 in libfreerdp2.so.2.0.0[7fbc84b1c000+137000]

I contacted one of the upstream authors on this.
