GHCi can crash when tabbing a filename

The following sequence of actions:

1. Type :: I into GHCI
2. Press the tab key
3. Hold backspace to erase the resulting text
4. Repeat steps 2 and 3

May result in the following appearing in the console:

Prelude Data.Map> :: ImageExpo.config ghc.exe: panic! (the 'impossible' happened)
  (GHC version 7.6.3 for i386-unknown-mingw32):
        Prelude.chr: bad argument: (-947713851)

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

followed by the system prompt.

Afterwards I have realised that :: was actually interpreted as a GHCi command rather than the type designation syntax. Tabbing yields all files in the current directory, but actually performing the command yields unknown command '::'

There is only one file that starts with I in my current directory.

Did not manage to reproduce
