Funny enough, it was a fix for a bug in the software (“gnome-blog”:http://www.gnome.org/~seth/gnome-blog/) I am using to write this post.
It was mostly a matter of figuring out what was failing–a GConf interface was failing when the app tried to store an integer–and then searching around “Mark Pilgrim”:http://diveintomark.org/’s excellent (and freely-available) “Dive Into Python”:http://diveintopython.org.
If I was really together, I’d post a patch, but I didn’t back up the original.
