We get this javascript error: 'plotX' is null or not an object. With the combination of a lot of null data and setting connectNulls to true.

Tested this on IE8 and Chrome

Steps to reproduce;

1. http://jsfiddle.net/9kCc5/
2. Zoom in and out on different places in the graph until you get the error message in the console: 'plotX' is null or not an object
3. The navigator-handles move along with mouse movement and won't release from it.
