Comment 9 for bug 1876344

I have attached an unreleased version that contains an extra line of additional debugging information that could help determine what is going wrong with this particular camera.

Please do this:

Delete all the files in ~/.cache/rapid-photo-downloader/log

Uninstall the Arch packaged Rapid Photo Downloader, but not its dependencies (very important).

Install Python pip and Python wheel if they're not already installed

Install the attached tar file (do not use sudo):
python pip install --do-deps rapid-photo-downloader-0.9.24.tar.gz

Ensure only the Fuji Fujifilm X-H1 is on the system (no other SD cards, cameras etc.)

Run:
~/.local/bin/rapid-photo-downloader

After the thumbnails fail to generate, from within the program run Report a Problem, and click save to create a tar file with the saved log and config files. Attach that tar file to this bug report.

When you want to uninstall this version, use pip:
pip uninstall rapid-photo-downloader
