ripit 3.8.0 bug and patch

[Ulli Horlacher]

When ripit (from Ubuntu 10.04) does not find a CD within freedb it gives an error:

        RipIT version 3.8.0.

        Will create a playlist file.

        Checking for a DB entry @ freedb.freedb.org...
        Odd number of elements in hash assignment at /tmp/ripit line 1137.
        Use of uninitialized value in list assignment at /tmp/ripit line 1137.

This patch fixes the bug:
