I’m getting the error message;

/usr/local/lib/ruby/1.8/date/format.rb:598: [BUG] unknown node type 0  
ruby 1.8.3 (2005-09-21) [i686-linux]

Aborted

This has been reported earlier:  
[http://rubyforge.org/tracker/index.php?func=detail&aid=2517&group\_id=426&atid=1698](http://rubyforge.org/tracker/index.php?func=detail&aid=2517&group_id=426&atid=1698)

but seems not to have resolved.  
My script uses date, rio and tk, is 885 lines long and I don’t succeed  
in  
reducing it - even removing the comment-only lines makes the problem  
disappear. What can I do (other than removing the comments ;-)?
