I've been seeing the same problem when trying to upgrade an application
from Rails 2.1.2 to 2.2.2. I had set up a controller to serve static
content wrapped in the site's template. One of the users dropped some
JPEG files into the /app/views/static directory, and that seems to be
jamming up the works with 2.2.2.

Now I know how to solve the problem (by removing the the non-.html.erb
files), but I'm wondering why there is a difference between 2.1.2 and
2.2.2.

2.2.2.

Theoretically it was to allow for all the erb templates to be loaded up
once at load time [it just happens to attempt this weirdness with non
erb files, too...I'm not sure if it's a bug or not...I believe I filed a
report of it on lighthouse].
Cheers!

Is there any way to exclude certain template file types (or non-
template files) from being preloaded, say by their file type?
Specifically, I was thinking of jpeg, swf files, etc. which we do not
(!) wish to be loaded/parsed at startup time.
Could there be a configuration option which handles this?

I think that trunk was updated recently to handle them better [i.e. only
.rhtml -> compile].
