[Haskell-beginners] Could not find file in module graph

[Øystein Kolsrud]

Hi! I'm using version 2.0.4 of Eclipse FP and I very often get an
error saying "Could not find file in module graph.". I did a quick
search on the web for this message, but all I could find was some old
threads discussing an issue with this symptom (for instance
http://code.google.com/p/scion-lib/issues/detail?id=36#c1). Does
anyone know what the error means and how I can avoid it?
