The AfterGlow application had to be updated to work with Splunk 4.2.x. There is a new release as of January 5th 2012 (version 1.6.2) which works with Splunk 4.2.x!
Please DOWNLOAD THE NEW RELEASE!
Also do not read the instructions in the Splunk blog entry about how to make the application work. Read the README file that comes with the app and is places in $SPLUNK_HOME/etc/apps/afterglow/README. You basically have to change two parameters in the AfterGlow.py file (AFTERGLOWLOCATION and AFTERGLOWPARAMETERS) to make things work.
See you on http://secviz.org!
