Newlines in error_log

I've got a little problem with the error reporting of mod-ruby. It was 
working correctly before, but I upgraded to apache and mod-ruby, and now 
my error messages are all appearing on one line like so:

[Thu Jun 24 18:17:17 2004] [error] mod_ruby: error in ruby\n/usr/lib/rub
y/site_ruby/ruby-general/INI/INI.rb:136:in `test': Insecure operation -

When previously they had been appearing nicely formatted like this:

Any ideas how I can get the escape characters to be interpreted again? 
As you can imagine, it makes debugging kind of hard.
