Where is editor presentation broken WebUI [ solved but for future generations ]?

As I was writing this I got the solution, but having spent the time decided to share....

User reports that cannot view work items.  I've pinned it on Defect work item type.  Inspecting the presentation and binding look reasonable.  But in Firefox I get a JavaScript error "TypeError: _e[_d[i].slot] is undefined"
Tracing in WebConsole get's to this section

var _e={"details":[],"linkSummary":[],"quickInfo":[],"defaultSection":[],"description":[],"discussion":[]};
for(var i=0;i<_d.length;i++){

It turns out there was an empty Section under the Overview tab.  I removed it, saved and now I can load/view defect work items.

Thanks Kevin for sharing solution!

What I can add is that you can append ?debug=true in address bar to have the code not obfuscated. It is easier to debug it then.

Cool,  I thought I added the ?debug, but didn't see much, now I know what to look for!  But having had similar experience, I at least knew to focus on the Editor Presentationn
