string-index defined twice?

[Eric Gillespie, Jr.]

% guile
guile> string-index
#<primitive-procedure string-index>
guile> (string-index "/path/to/blah" #\/ 1)
5
guile> (use-modules (ice-9 slib))
guile> (require 'cgi)
guile> string-index
#<procedure string-index (str a-char)>
guile> (string-index "/path/to/blah" #\/ 1)
ERROR: In expression (string-index "/path/to/blah" #\/ ...):
ERROR: Wrong number of arguments to #<procedure string-index (str a-char)>
ABORT: (wrong-number-of-args)

Type "(backtrace)" to get more information or "(debug)" to enter the debugger.

This happens with both Guile 1.4 and 1.5.4.  I found the
redefinition of string-index in ice-9/format.scm.  Which
definition is correct?  Can this be fixed before 1.6?

Thanks.
