From a mail from Waldo pointing out two probs in Thumbview:
1) KDirLister is the owner of the KFileItems it emits, this means
that you must watch it's deleteItem() signal vigourously,
otherwise you may end up with KFileItems that are already
deleted. This burden is propagated to classes that use
KDirLister, such as KFileIconView.
This has a tendency to go wrong in combination with PreviewJob,
because it stores a list of KFileItems while running. This has
the potential to crash if the fileitems are being deleted
during this time. The remedy is to make sure to remove
fileitems that get deleted from the PreviewJob with
PreviewJob::removeItem.
