Thanks. My guess was correct: the buffer in question was killed.Could you please try the patch below, and see if it avoids thecrashes? The patch causes Emacs to signal an error whenformat-mode-line is called for a dead buffer, so if I did thiscorrectly, you should see that Emacs no longer crashes, but there areerror messages about a dead buffer in *Messages*. If this is whathappens, you should then take this up with the dirvish developers, andask them to avoid calling format-mode-line for a killed buffer.
Thanks! The patch prevents the crash. I will report this to dirvish developers.
