-xc giving very little information

[Stefan Reich]

A complex program of mine fails with this message:

	Fail: Maybe.fromJust: Nothing

I tried to extract more information about the error by compiling with 
-prof -auto-all and running the program with +RTS -xc, as advised on 
http://www.haskell.org/hawiki/TipsAndTricks . This yielded exactly one 
additional line:

<Data.Maybe.CAF>.
Fail: Maybe.fromJust: Nothing

(Same result for GHC 6.0.1 and 6.2.)

Is there another option I have to use to get a full stack trace? Or is 
my longing for stack traces a side-effect of writing too much Java code 
that I have to overcome? :)
