gdk-pixbuf-2.0 - Loaders cache unpopulated

[KiralyCraft]

I've just installed Arch on my RPI4, manually configuring it as a 1:1 clone of an x86 machine for a thin client based on virt-viewer and openbox. When installing, I noticed that `/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache` was empty, which caused some missing icons. It seems that after calling `gdk-pixbuf-query-loaders` manually with the `--update-cache` parameter, this file got populated, which in turn restored the icons.

I've never had to do this on the x86 version. I wonder, what is the normal procedure for this cache to be populated? The `update-mime-database` command did not fix this, and I had to `strace` into `remote-viewer` to see what went wrong, to discover the `loaders.cache` file and to populate it accordingly.

Why did this cache not get updated automatically?

Attaching a list of installed packages.

All I have ever had to do is edit the one line by adding a comment in /etc/pam.d/system-login:

$this->bbcode_second_pass_code('', '#%PAM-1.0

I also had the same problem and luckily I found your workaround on the mesa-21.2.1 forum worked again.
