Build: NetBeans IDE 7.1 (Build 201112071828)
VM: Java HotSpot(TM) 64-Bit Server VM, 20.4-b02-402, Java(TM) SE Runtime Environment, 1.6.0_29-b11-402-11D50
OS: Mac OS X

User Comments:
sworisbreathing: I had two files in my project's git repository which I wanted ignored.
I exited NetBeans and ran "git rm --cached <filename>" for each of the files on the command line.
I then reopened NetBeans, selected both files (under the "Files" window), right-clicked, and selected Git->Ignore from the popup menu.
Once this finished, I opened up the IDE Log because I wanted to see what command had been run.  That's when I first noticed this error.
