Can you retest with KF 5.56?
If you can provide the information requested in comment #2, please add it.
(In reply to Christoph Feck from comment #3) > If you can provide the information requested in comment #2, please add it. I update kde neon user edition regularly. The bug is still there.
Can you determine the crashing file using balooctl monitor?
(In reply to Alexander Stippich from comment #5) > Can you determine the crashing file using balooctl monitor? Using balooctl monitor, I have realized that the indexing process stopped always at the same file. This was actually a corrupted jpg file. I've deleted it and after restarting baloo, everything works fine. Thank you for your suggestion!
Can you upload the corrupted file so that I can try to reproduce?

(In reply to Alexander Stippich from comment #7) > Can you upload the corrupted file so that I can try to reproduce? I had a copy of the file on another hard-disk and yes, the crash is reproducible (at least on my pc). I can add that the same file was also on another pc (synced with Unison) where I had no problem with baloo (maybe, the file had been stored on the baloo index there before something bad happened or the two copy passed the Unison sync procedure but they were not exactly the same...). Anyway, please find it attached on y previous message.
Thank you very much for attaching the problematic file!
