XCF issues and more

[Carol C. Kankelborg]

Hi,
   I recently upgraded to DigiKam 8.7.0 (Build Date 6/29/25 09:49), running on Sonoma 14.7.6. I ran the maintenance tools to clean up the database and rebuild thumbnails & fingerprints.

  Before upgrading, there were a bunch of .xcf files that were grouped together under 100% similarity but were clearly very different from each other. After upgrading, these same files are grouped together in similarity, but the thumbnails and preview in Digikam is blank (all white). This doesn’t affect all of my .xcf files. As an example, I have one file I edited with Gimp from a scan from 11/3/22 that looks blank and another from 11/4/22 that looks fine. The blank one looks fine when I open it in GIMP. 

  Is this a bug I should report or is there some setting that is throwing DigiKam off?

  I sent the above question with a sample .xcf file that was too big so it is awaiting moderator approval. I decided to scale down the image in GIMP and import it into DigiKam to see if it still had the problem, so I could resend my question within the size limits. I encoungered more bugs.

First, DigiKam crashes when I try to create a new album, even though it does successfully create the new album.
Second, when I try to “Add Images” to put the new .xcf file in DigiKam, it asks which album, then does nothing. The same thing happens when I try with a .jpg.

I created an account on bugs.kde.org <http://bugs.kde.org/> to search for these issues, but didn’t find anything. The bug page was a bit intimidating — I have no idea what component to report, so I decided to check in here to see how best to proceed. 

Here is another oddity I’ve experienced, so I’ll just throw it in here in case anyone has any insights.

Somewhere along the way DigiKam lost track of two albums. They were in the Collections file tree, but weren’t showing up as albums. I ran a “find new items” scan and they re-appreared. I don’t know if they disappeared before or after I upgraded to 8.7.0.

I have Full Disk Access turned on for DigiKam.

Any help with these would be appreciated.
