[Haskell-beginners] exceptions and stacks

[Emmanuel Touzery]

well studying it further it seems the output I got was:

<GHC.List.CAF>TvChannelsParse: Prelude.head: empty list

It was a bit difficult to extract it because the normal output of my
program is really flooded by extra text from the RTS options.

So I get this GHC.List.CAF extra information; not particularly useful (I
mean for sure the head fails in GHC.List, I already knew that). I see
others got the same as I did:

 So maybe there is nothing to expect from that profiling trick after all...
