ruby 1.8.2 (2004-12-25) [i386-mswin32]
latest version of edge rails - patched to make the server work with
win32 (http://dev.rubyonrails.org/ticket/4139)
On some pages WEBrick is crashing with the following:
d:/programming/ruby/lib/ruby/1.8/profiler.rb:27: You have a nil object
when you
didn''t expect it! (NoMethodError)
You might have expected an instance of Array.
The error occured while evaluating nil.[] from
d:/programming/ruby/lib/rub
y/1.8/profiler.rb:5:in `require''
from script/server:7:in `require''
from script/server:7
Any ideas on what''s happening, or tips on tracking this down would be
great.
Here''s the full output (not especially pretty formatted I''m
afraid due
to wrap):
