Summary: NullPointerException on Scroll

Initial Comment:
Sorry, I haven't been able to find a way to reliably trigger this bug, but sometimes when I do search & replace operations, afterwards, trying to go to the end of the buffer will throw this BeanShell error:

Possibly related to bug #1775258
(https://sourceforge.net/tracker/?func=detail&atid=100588&aid=1775258&group_id=588)
which was closed?

This doesn't require any wrap mode to be triggered.

It's not helpful, but I too encounter this bug on a fairly regular basis. 
I end up saving my file and reloading.  Gotta love that F5 key . . .

Still current as of 'ant deb' with r11790.
