Comment 15 for bug 1950673

You would have to treat me as knowing nothing in order to obtain a log I'm afraid.

It does occur with every book I've tried to open for quite a while now. It's not limited to one, or a few books.

As I said in my initial post, I'm running Calibre 5.31.1 64 bit, and the problem started with the release before that. Prior to that I'd never encountered an issue like this in years. Something that changed between those releases would appear to the cause then.
