HTTP ERROR: 404 when accessing messages from search or user listing

[tmetro]

I've ran across broken links on both Nabble search results and the pages that list a user's postings. For example, the page listing my postings:
http://old.nabble.com/user/UserPosts.jtp?user=1373902&i=175

Links to a message at:
http://old.nabble.com/chrome-tp27189479s24859p27235482.html

which returns:
  HTTP ERROR: 404
  NOT_FOUND
  RequestURI=/chrome-ts27189479i20s24859.html
