Not seeing image previews in Win AIO 6.0.7

Help
1

I’m using Win AIO 6.0.7 on Win 11 Pro.

My version of Gramps knows the media type image/jpeg but I can no longer see previews of images, all I get is a generic icon that looks like:

I’ve tried removing the media and adding it again but there is no change.

Any clues?

I have rolled back to v6.0.6 and the previews are working again.

3

I am seeing no thumbnail generation on new pictures displaying the generic documents.png.

Older pictures with an existing thumbnail generated pre-6.0.7 display normally.

4

I can’t see any bug fixes in v6.0.7 that relate to the thumbnailer.

5

Is it not more likely down to the problems with getting a Windows 6.0.7 build to work?

6

I don’t think we have an official 6.0.7 installer for Windows yet. So yes.

7

Unless it’s been pulled, there is a 6.0.7 AIO installer on GitHub. I assumed therefore it was an official relesse, hence I used it.

Please file a bug report so that the issue can be tracked down. Thanks.

Just to correct an earlier statement, there is an official gramps 6.0.7 release which is availble from both the gramps website and github.
I can reproduce this problem using my own gramps 6.0.7 installation. The error shown in the console is

2026-03-31 21:15:19.114: WARNING: imagethumb.py: line 99: Error scaling image down: Unable to marshal str as an array, use .encode() to convert to bytes

To reproduce the problem:

  1. create a new gramps database
  2. From the menu select Add > Media
  3. Select a supported media file
    No thumbnail will be shown on the right hand side of the dialog

There is a proposed fix for this problem by @dsblank See Fix imagethumb savev() passing strings instead of lists for array args by dsblank · Pull Request #2204 · gramps-project/gramps

I’ve confirmed that with this change on gramps AIO 6.0.7, thumbnail images are generated again.
