`!xcb_xlib_threads_sequence_lost' failed. Status in “remmina” package in Ubuntu: Confirmed Bug description: I was connected to Ubuntu Server 10.04 via Remmina SSH, when the crash occurred. Specifically, I had just typed exit at the command prompt to end my SSH connection with one Ubuntu server and then double clicked another Ubuntu 10.04 server session in Remmina when the crash occurred. My guess is that the issue occurred in the background when I exited the first ssh session prior to attempting to access the second connection.
