First appeared in 5.16.1. I have a custom field (Date Read) that I populate when marking books completed. The error code states:


calibre, version 5.16.1
ERROR: Unhandled exception: <b>AttributeError</b>:'NoneType' object has no attribute 'year'

--------------------------------------


The Column Type is Date
Format for dates is M/d/yyyy
Default value is empty

Other items: Lookup name is read-date; Column heading is Date Read


Up to this version (many years) I would open field not enter anything then tab and it would populate today's date. Now I open field get the error, hit OK tab and it populates today's date. Minor error but may bite something going forward.
