 The Journal should behave gracefully on entries with unexpected (but
 syntactically valid) metadata, currently it shows a random colour icon
 that colour strobs as you move your mouse over it and a 0% grey download
 progress bar. See attached screenshot and ticket #1407 for a current
 example.

 Perhaps a broken icon, a palette option allowing erase and using the data-
 store entry directory hash as a fallback for the title title would would
 help both debugging/support feedback, and allow users to remove the broken
 entry via the UI, if that's what they want.
