--- Comment #6 from Mick Sulley <m...@sulley.info> --- Unfortunately I have largely destroyed the evidence by creating new sub albums and copying the pictures. However I thought I would try to see if I could find out anything using the new appImage. It gets a bit complicated, sorry. This is what I did - Created a guest user on my desktop (runs Mint18) Copied my whole album to the guest account Downloaded appImage5.4.0 Within the Album I have digikam4.db, my current database and digikam4.db.backup which was the one in use when I had the problem. I renamed digikam4.db as .old and renamed digikam4.db.backup as digikam4.db to make it current again. I then started DK5.4.0 The sub-album that had pictures missing is displayed, even though it no longer exists! It has thumbnails in it, but if I double click any I get the message 'Failed to load image' File properties shows the folder that was where the picture was, but that folder no longer exists. I ran Rebuild Thumbnails and also Scan for new items from Tools > Maintenance, the indicators on the bottom of the screen went up to 100% in a few seconds, however it took more than 2 hours before it actually finished. When it had finished I see the original structure with boxes displayed for thumbnails and all the property information but no metadata. There is no thumbnail and double click produces the message 'Failed to load image'. Presumably this is because the database holds all of this information. I then ran Sync Metadata and Database, but that doesn't seem to have changed anything. My conclusion to al this is that my original problem was caused by a database corruption, what caused that I don't know. I don't really see any point in pursuing this any further so I suggest that you close it. Thanks Mick -- You are receiving this mail because: You are watching all bug changes.
