I am trying to shoot in the dark. I have never come across this issue, even though I have been juggling around a bunch of dev accounts.
Once your keychain and organizer are clean,
Try to get your mac spotlight to reindex (search something in the spotlight, select the last row), in the privacy tab, include the MacintoshHD (and any other drives indexed) in the list of locations preventing spotlight to index
repeat the steps above and remove the Macitosh HD from the same list, so that a fresh index is created.
Let me know if this makes any difference. (I had a similar issue, and this solution worked)
