thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', libcore/option.rs:355:21

I had this script working for over a month now without having any problems. Now suddenly I get the following output:

$ dyn-wallpaper-linux "Bern" "/home/mau/Pictures/Wallpapers/Mojave" 
16 images found in /home/mau/Pictures/Wallpapers/Mojave
Output file: "/tmp/dyn_wallpaper.jpg"
Selected city: Bern
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', libcore/option.rs:355:21
note: Run with `RUST_BACKTRACE=1` for a backtrace.

And the output with Backtrace:

$ RUST_BACKTRACE=1 dyn-wallpaper-linux "Bern" "/home/mau/Pictures/Wallpapers/Mojave"
16 images found in /home/mau/Pictures/Wallpapers/Mojave
Output file: "/tmp/dyn_wallpaper.jpg"

I also tried something like this and got the same error: dyn-wallpaper-linux "Bern" "/home/mau/Pictures/Wallpapers/Mojave" "feh --no-fehbg --auto-reload --bg-scale {path}"

I didn't make changes to my system recently so I have no clue what the problem might be. I use an up to date Manjaro Linux with i3wm so setting an image directly with feh works well.

I hope you can help me troubleshooting this issue, as I loved this background!

Since yesterday morning it's working well again. I have no idea what changed that this issue popped up. I'm closing this for now.

[panmona]

Somehow this issue appeared again now with the same symptoms. I'm not sure why and how to actually resolve it for good. Maybe some recent package updates caused it but not sure which exactly...

[Pitasi]

hi, sorry to hear this problem happened again

what you're thinking of a recent package update? did you recently rebuilt the dyn-wallpaper binary?

[panmona]

No, I didn't change the binary since I started using this.

I was thinking that some Arch Linux package I updated recently interferes here but nothing looks suspicious from my update log (grep -i installed /var/log/pacman.log).

A restart seems to have fixed it again though. Not sure what is happening here.
