This is the crash:
ERROR: [xcb] Unknown request in queue while dequeuing
ERROR: [xcb] You called XInitThreads, this is not your fault
ERROR: [xcb] Aborting, sorry about that.
ERROR: Thrive: xcb_io.c:175: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
xcb is a part of the X11 windowing system. So I think this is is a rare engine bug or specifically with your windowing system etc. versions clashing with what Godot is trying to do.
