前言
运行GUI程序出现报错如下，
(gnome-calculator:4038): Gtk-WARNING **: 06:23:42.942: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

就像报错信息所提示的那样
This may indicate that pixbuf loaders or the mime database could not be found.我们从gtk3、gdk-pixbuf、mime database等几个方向进行排查
首先检查XDG_DATA_DIRS，确保不要在.zshrc（或bashrc等）中设置XDG_DATA_DIRS，
不要在XDG_DATA_DIRS中包含flatpak的path
echo $XDG_DATA_DIRS的一个参考结果如下
/home/user/snap/alacritty/46/.local/share:/home/user/snap/alacritty/46:/snap/alacritty/46/usr/share:/usr/share/awesome:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop重新安装一些包，并且重新配置，并且标记为自动安装
