Looks like the issue is in KFileMetaData or poppler, which is crashing while trying to parse a document for content indexing. Any chance you can attach the PDF file causing this crash? You can find it by running `balooctl failed` in a terminal window?

Obviously if the document contains sensitive atomic secrets, don't attach it. :)  But then it will probably be difficult or impossible to fix the issue, unfortunately.

Thank you for your efforts. However, "balooctl failed" returns "All Files were indexed successfully".

Hmm, thanks anyway.

Comment 4 aawasthi 2023-08-23 05:23:02 UTC

The bug has disappeared on reinstalling "Poppler" package, which provides "libpoppler.so.123".

Comment 5 Nate Graham 2023-08-23 15:47:55 UTC

Cool, I guess it was a local installation or configuration issue.
