Redmine

When attaching files with special characters (ampersand is an example), the attachment link does not work:

attachment:"Test & Show.txt" 

The regular expression in application_helper.rb, parse_redmine_links does parse the filename correctly but it seems that the code that compares attachments to the filename fails to match the two.
