Okay, I spoke too soon, and I do have that output for you.

Note that the simple activate script wasn't triggering the workflow crash, but this is the script that was:

tell application "iCal" to quit
tell application "OmniFocus"
	activate
	tell default document
		tell front document window
			set perspective name to "starting soon"
		end tell
	end tell
end tell
tell application "end of the day" to activate

Here's what results from your procedure when the workflow containing this script is run (and crashes):

user$ AEDebugReceives=1 /Applications/OmniFocus.app/Contents/MacOS/OmniFocus
