This is caused by the first (error ...) call in viper-event-key in 
viper-util.el which signals when an "event" is issued that is not really 
an event; in this case, a buffer name string.  Of course, this "event" 
came from somewhere else, but I couldn't track it down.  Mainly because 
setting debug-on-error never produces a backtrace for these errors?!? 
So, I just replaced the (error ...) call with (setq event t).  No idea, 
what I did, but I haven't seen the error since, but I'll keep looking.
