Search'n'replace intermittent error

[Sergey Organov]

Hello,

Sometimes, when I run query-replace (M-%) in a buffer, I get an error
that, after turning debug-on-error to 't, looks like this:

Debugger entered--Lisp error: (args-out-of-range #<buffer 
Makefile<linux-driver>> 0 1)                        
  buffer-substring-no-properties(0 1)                                           
                              
  perform-replace("br_rev" "BR_REV" t nil nil nil nil nil nil nil nil)          
                              
  query-replace("br_rev" "BR_REV" nil nil nil nil nil)                          
                              
  funcall-interactively(query-replace "br_rev" "BR_REV" nil nil nil nil nil)    
                              
  call-interactively(query-replace nil nil)                                     
                              
  command-execute(query-replace)                                                
                              

Does this ring a bell? I've tried to look at the code, but it's rather
convoluted and I can't easily figure how to fix it.
