Yes - that was the first place I looked. Obviously.

As far as I can tell, from observed behaviour and from inspecting the =

code, an error in the prepare phase does not generate any response. I =

simply get an empty reply. I have checked this using curl as well as a =

browser. Errors later on seem to work fine.

The Catalyst::Action dispatch method does use the execute wrapper. =

However, I can find no error protection for the prepare phase. Since =

this issue is caused by a plugin failing during that phase, I get no =

error display through the browser. Tried from curl, I get:

> C:\workspace\ARM>curl http://localhost:3000/index
> curl: (52) Empty reply from server

I suggest this is a serious issue, but I cannot claim to have a strong =

enough grasp of the overall architecture to suggest how to resolve it =
