I have an issue where I select 100 PDF files to embed metadata. If one of the files is broken, then the embed STOPS processing everything else, but could take 10 minutes to actually seem like it finishes. Only to display an error.

I know it stops, because I am testing with some known bad PDFs to verify the behavior. I would expect an error list of broken files while the rest succeed, but the behavior is that Calibre Embed appear to continue but actually not proceed past the first broken file. I have to fix the file then reselect the PDFs and start the embed process again to continue.

The whole process breaks after the error, but seems to simulate continuing, doesn't collect any more logs for other broken PDFs and doesn't LOG ANYTHING in the DEBUG log. This program really needs better logging.
