> A NPE was thrown when I tried to view the simple history for the file system connector. This happened after I tried to delete the connector itself and its belonging jobs.
> Apparently I managed to delete the jobs since they went away from the job list, but their status were still in the "cleaning up" state. Entries like this were shown in manifoldcf.log:
