Spotify doesn't like spotio's icons.

[Pival81]

I maintain the spotio package on the AUR, and wanted to use a modified .desktop file and icons instead of the default spotify ones. So this morning i worked to replace all the icons, but spotio doesn't want to use them. Here are the file permission of normal spotify:

-rw-r--r-- 1 root root  24K  1 set 18.45 spotify_icon.ico
-rw-r--r-- 1 root root 8,0K  1 set 18.45 spotify-linux-128.png
-rw-r--r-- 1 root root  890  1 set 18.45 spotify-linux-16.png
-rw-r--r-- 1 root root 1,2K  1 set 18.45 spotify-linux-22.png
-rw-r--r-- 1 root root 1,4K  1 set 18.45 spotify-linux-24.png
-rw-r--r-- 1 root root  17K  1 set 18.45 spotify-linux-256.png
-rw-r--r-- 1 root root 1,7K  1 set 18.45 spotify-linux-32.png
-rw-r--r-- 1 root root 2,9K  1 set 18.45 spotify-linux-48.png
-rw-r--r-- 1 root root  26K  1 set 18.45 spotify-linux-512.png
-rw-r--r-- 1 root root 3,2K  1 set 18.45 spotify-linux-64.png

And the window icon is right: And here are the spotio's file permissions and screen:

-rw-r--r-- 1 root root 9,5K  9 set 10.41 spotify_icon.ico
-rw-r--r-- 1 root root  14K  9 set 10.41 spotify-linux-128.png
-rw-r--r-- 1 root root  604  9 set 10.41 spotify-linux-16.png
-rw-r--r-- 1 root root 1,1K  9 set 10.41 spotify-linux-22.png
-rw-r--r-- 1 root root 1,5K  9 set 10.41 spotify-linux-24.png
-rw-r--r-- 1 root root  28K  9 set 10.41 spotify-linux-256.png
-rw-r--r-- 1 root root 1,5K  9 set 10.41 spotify-linux-32.png
-rw-r--r-- 1 root root 3,7K  9 set 10.41 spotify-linux-48.png
-rw-r--r-- 1 root root  86K  9 set 10.41 spotify-linux-512.png
-rw-r--r-- 1 root root 5,3K  9 set 10.41 spotify-linux-64.png

Also, it says that spotio's missing the spotify-linux-512.png file in /usr/share/spotify/icons , while it clearly is there.

The output of spotio. The output of spotify.

Maybe spotify has a built-in hash checker for his files?
