Yes, see below.

AFAICT, it shouldn't even try to run "bzr status" on this file, since
it's a temporary file used by bzr for the commit message.  But if it
somehow must run "bzr status", then it shouldn't signal an error when
it predictably fails.  But maybe I'm missing something.

Debugger entered--Lisp error: (error "Running bzr status 
bzr_log.ahvp69...FAILED (status 3)")
  signal(error ("Running bzr status bzr_log.ahvp69...FAILED (status 3)"))
