Darktable exports one image and then just hangs

[Smartich0ke]

Describe the bug

I'm trying to export a batch of images at once in the lighttable view. I select the images I want and hit export. The first image exports successfully and then nothing happens. The progress bar in the bottom left corner is just stuck on "exporting 2/n...". It's really frustrating because I have to now manually export each image one at a time.

Steps to reproduce

1. Got to lighttable view
2. Select some images to export
3. Open the export module, hit "export"
4. Wait and experience the pain

Expected behavior

That Darktable exports the images

I didn't have this issue with previous versions.

maybe add a log file (e.g. by running darktable -d common from terminal) so someone can get an idea, what‘s happening on your system …

Hi, I ran darktable with the -d flag. This time export results in another text showing up below the "exporting 1/n image..." popup saying something like "borders has an introspection error" and nothing gets exported. I am using the appimage version.

The logs are huge so I put them in a pastebin:

I am having the exact same issue. DT is utilizing the CPU but even after waiting for 10 minutes it did not continue exporting images. Stuck at 902/2544. darktable -d all is not showing anything when DT is stuck exporting. No new messages posted to terminal. My system info:

Using darktable v5.0.0 from the pacman extra library.

Tried disabling OpenCL but that didn't make a difference.

I've tested with darktable-cli and the result is the same. Export gets stuck and no warning/error messages displayed. Interestingly, darktable process is utilizing the CPU when it gets stuck.
