Mapping next-result to ^n goes down twice

[pfaffman]

If next-result is mapped to control-N when ^n is pressed in a list of items the cursor goes down two lines. Mapping previous result to ^P similarly goes up two items. My solution has been to map previous-result to Up, allowing me to get to the second result in the list with ^N followed by Up.

This is true in the stock Ubuntu 14.04 and in both 14.04 and 14.10 with the bleeding edge ppa version.
