Hello to all.

I wonder if someone is able to help me out. I'm using the RSCM gem to 
help us with our deployment and am running into some difficulties when 
using RSCM::Subversion.diff to get the changes made since a "base" 
revision.

When i call RSCM::Subversion.diff i get the following error:
*/
scm.diff("branches/optimization/Rakefile", 1533, 1665)/*

/svn: Can't write to stream: The pipe is being closed. 
c:/ruby/lib/ruby/gems/1.8/gems/rscm-0.5.1/lib/rscm/command_line.rb:111:in

/However if i copy the svn diff cmd from the error codeand run it from a 
command line, I get a diff of the files as expected.:

*/svn diff --revision 1533:1665 
"svn://svn.******/Ruby/****/branches/optimization/Rakefile"/*
/
/I'm running Ruby 1.8.6 on Windows XP with the RSCM v0.5.1 (oh and 
Subversion 1.5.1). If i've missed anything let me know. Would really 
appreciate help if anyone can.

Cheers
Jim
