A problem occurred <<server died>>

[gcharnock]

I managed to get this project to build, but when I try and run it I end up with a big, orange page that says "A Problem Occurred".

Steps are:

$ stackage-view
Point your browser to http://localhost:3000/

I chose to point it at its own source code. Visiting localhost:3000 with a browser results in the usual "Chose Targets" screen with the choices "Library, Executable, Test suit". Selecting any combination and hitting "done" results in the orange screen. All further interaction (F5, visiting in another tab) goes directly to the orange screen.

The logs printed to the command line look normal, but I'll include them just in case:

I should also mention that ide-backend-server seems to have problems. I don't know if that's related or otherwise causing this problem.

$ ide-backend-server
ide-backend-server: IdeSession/RPC/Server.hs:49:7-27: Irrefutable pattern failed for pattern errorLog : fds

Indeed, the orange screen will come from the server not replying to the client properly (e.g. closing the connection), which probably happens due to ide-backend-server failing like that. Can you report that to ide-backend?
