[Solved] xdg-open 'one_png.png' was changed since last pacman -Syu

Before today, ".png" file opened by Image Viewer, but since today's update,
it opened by a "Wine Internet Explorer", in fact,  those old IE browser can't
open any png file!

any idea on why this change? thank you!

Define your default applications properly:

https://wiki.archlinux.org/index.php/XD … eapps.list

If you never did any explicit configuration here it can potentially flip-flop with every update

If you install any application in Wine, it will per default make desktop-environment wide file associations (on your host desktop environment) in case the application wants to make them during install.

This is a nuisance, and most often not what is needed (it would make sense on a dedicated windows machine, but I can see there are exceptions for different use cases and sometimes the associations are a wanted feature). I often find something annoying happening, for example all .txt files (and other extensions which are considered text) are opened in some wine application, in case I've reset .wine (or used another WINEPREFIX) and forgotten to disable before installing something.

You can remove all file associations made by wine and prevent wine from making any new ones in the future, in case you install a new application in wine.

Not sure if this is your problem, but it sure sounds like this!
