I faced a strange bug for several days.
Everytime me (or a program) was using
xdg-open to open a folder, it was opening…Audacious! What the heck!
The error comes from the mimetype which has been set wrong at some time (not sure when):
$ xdg-mime query default inode/directory audacious.desktop
To fix it, just enter this in a terminal:
$ xdg-mime default dde-file-manager.desktop inode/directory
(feel free to replace
dde-file-manager.desktop by the .desktop of your favorite file manager program ^^)
I’m not sure this is an error from Antergos or just Deepin in general. In all cases, I post it here in case someone runs into the same problem.
