Run digiKam in DebugView as explained here :

https://www.digikam.org/contribute/#windows-host

And report the trace in this file.

The table view allows you to configure which properties are displayed. You may have removed the thumbnail column. You can add it back by right-clicking on the table header.

The first time, I did not see the "Clear Button on Debug Viex.
I started again, with Clear just before starting Digikam.
I send you  another one, where I open, and close digikam

Thanks for the log file. Your thumbnail database is corrupted, and it can't really be repaired. Just delete your "/leneuf/home/Drive/PhotoScan/thumbnails-digikam.db" file; it will be rebuilt on the fly. Also check the hard drive where it's stored. I've never personally encountered a corrupted SQL database with this error message: "database disk image is malformed."

Comment 13 Maik Qualmann 2025-06-01 18:55:26 UTC
Using SQLite over a network drive isn't a good idea. WAL mode shouldn't be enabled either. Even concurrent read access can corrupt the database on the network drive. You should consider migrating to MySQL. I'm closing this bug now.
