Summary: File.basename bug smoked out by WEBrick, Rails

Initial Comment:
It looks like there's a bug in File.basename somewhere:

C:\>ruby script\server
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options
[2008-07-18 15:29:55] INFO  WEBrick 1.3.1

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

It was hard to track this down because adding print statemetns seemed to alter the behavior, but I did notice something like this:

Message:
Not sure what's happening now. I tried Rails 2.1 with win32-file 0.5.5, windows-pr 0.9.0 and win32-file-stat 1.2.7. With some debug print statements added to win32-file-stat, I narrowed it down to:

ERROR IN 'get_file_type' ON: C:\Documents and Settings\djberge\workspace\gym_tracker\config\routes.rb

This is strange because I can definitely stat that file. Thread issue perhaps?

Quick update - it's line 436 in 0.5.5:

file = file.split(0.chr).first
