404 issue with existing function

[eluser]jsuissa[/eluser]
I'm getting 404 errors for an existing function with routes setup.

I've included the relevant routes and URL excerpts below. The function 'details' exists in the 'items' controller.

Any insights as to why this may be happening would be greatly appreciated.

Route (first works, second fails):
$route['item'] = 'items';
$route['item/(:any)'] = 'items/details';

URL fails for details function:
http://www.example.com/index.php/item/in...gramming/1

URL works for index function:
http://www.example.com/index.php/item/
