[Koha] 24.05.03 A blank record opens when editing an existing biblio

[Elaine Bradtke]

This is an odd behaviour, and only involves *some* records. If I open the
existing record to edit it (basic editor), it opens a completely blank
record. It only happens while editing individual records. Koha internal
batch edits work as expected.
It seems to only affect a group of records that were uploaded about 10
years ago.  I'm planning to download and batch edit these in MarcEdit soon,
and could presumably fix the problem if I knew what fields were the
culprits.
Any thoughts?
