Doh! Your componentSearch catalog has at least one broken item in it.  
Try the following in zendmd. Run this script until you stop getting  
messages about things being removed.

# Fix componentSearch
brains = dmd.Devices.componentSearch()
for d in brains:
     try:
         bah = d.getObject()
     except Exception:
         print "Removing non-existent component from componentSearch:  
" + d.getPath()
         dmd.Devices.componentSearch.uncatalog_object(d.getPath())


# Make sure our fixes are saved
