Subject: Log4r with Ruby 1.8

Hi all,

I'm trying to use log4r ( http://log4r.sourceforge.net/contact.html )
but when running the example given at the site, I get an error (and I 
would like to know what I could do about it)

The example is like so (from the abovementioned web page):

> require 'log4r'
> include Log4r
> 
> # create a logger named 'mylog' that logs to stdout
> mylog = Logger.new 'mylog'
> mylog.outputters = Outputter.stdout
> 
> # Now we can log.
> def do_log(log)
>   log.debug "This is a message with level DEBUG"
>   log.info "This is a message with level INFO"
>   log.warn "This is a message with level WARN"
>   log.error "This is a message with level ERROR"
>   log.fatal "This is a message with level FATAL"
> end
> do_log(mylog)

Now, the should be this:

> DEBUG mylog: This is a message with level DEBUG
>  INFO mylog: This is a message with level INFO
>  WARN mylog: This is a message with level WARN
> ERROR mylog: This is a message with level ERROR
> FATAL mylog: This is a message with level FATAL

....but I get that:

C:/RUBY/lib/ruby/site_ruby/1.8/log4r/formatter/formatter.rb:58:in 
`sprintf': unnumbered(1) mixed with numbered (ArgumentError)
	from C:/RUBY/lib/ruby/site_ruby/1.8/log4r/formatter/formatter.rb:58:in

	from C:/Stephan/Programmierung/WegwerfSkripte/log4r.rb:12:in `do_log'
	from C:/Stephan/Programmierung/WegwerfSkripte/log4r.rb:18

Now I admit I'm quite not used to using sprintf...

Any ideas?

Cheers
