:print panics GHCi with overloaded values

After starting GHCi, using the debugger to print certain functions causes a panic. For example, the following statements all cause GHCi to panic and quit:

:print (+)
:print print
:print log

Other functions, such as head, tail, and fst are shown by the debugger properly as <function>, with no error.

This behavior is identical on PPC and i386 platforms, running OS X (10.4/10.5 respectively).
