Error during incremental search

[Peter Seibel]

Symptoms:

1. Enter the following text in an empty buffer, such as *scratch*

foo

2. Then position the point at (point-min)

3. C-s (isearch-forward) and type a character other than "f", or "o".

4. Observe the wrong-type-argument error.

After toggle-debug-on-error I get this stack trace:

Debugger entered--Lisp error: (wrong-type-argument integerp ["ba" "ba" 7 7 t 5 
nil nil nil 1 nil t])
  isearch-search()
  isearch-search-and-update()
  isearch-process-search-string("x" "x")
  isearch-process-search-char(120)
  isearch-printing-char()
  call-interactively(isearch-printing-char)

You can also reproduce this by searching first for characters that are
found (e.g. type "f" then "o") and then something that won't by (type
"x").
