GHCi: strange behaviour after CTRL-C, followed by 'hPutChar: resource vanished (Broken Pipe)' when quitting

Example: (launching GHCi from Terminal.app)

GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.

^CPrelude> 1+2
^CPrelude> :q
<stdout>: hPutChar: resource vanished (Broken pipe)

This behaviour does not occur when I run GHCi from within Aquamacs (some output elided):

GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help

I'm using the Haskell Platform for Mac OSX, 2012.2.0.0 32 bit, running on OSX 10.6.8.
