Hi,

I believe the sparse tree search is broken. It has been broken for a
while I think. Searching for tags returns no matches. I get the
following backtrace with debug enabled on a minimal emacs on using
`next-error' after a tag search which should return a positive result.


Debugger entered--Lisp error: (error "No more matches")
  signal(error ("No more matches"))
  error("No more matches")
  byte-code("`\305\"\211\2036  org-occur-next-match(1 nil)
  next-error(nil)
  call-interactively(next-error nil nil)



To replicate this, open the attached org file and search for the tag Qn.

C-c / m Q n RET

I tried running a quick edebug on org-sparse-tree, but I am having a
problem in answering the prompt and stepping forward with the edebug
simultaneously. Hopefully someone else will have a better luck.

Thanks,
