ghci :e throws exception after type error

After a type-error on the command line, :e starts throwing an exception. To reproduce:

~/src/ghc/inplace/bin/ghc-stage2 --interactive test.hs

GHCi, version 7.11.20150128: http://www.haskell.org/ghc/  :? for help
[1 of 1] Compiling Main             ( test.hs, interpreted )
Ok, modules loaded: Main.
*Main> 1 + ()

<interactive>:2:3:
    No instance for (Num ()) arising from a use of ‘+’
    In the expression: 1 + ()
    In an equation for ‘it’: it = 1 + ()
*Main> :e
*** Exception: <interactive>: canonicalizePath: does not exist (No such file or directory)
*Main> 

The contents of test.hs is not important as long as there is a file to edit.

Editing works fine before the type-error on the command line.
