Comment # 3 on bug 1106850 from Dr. Werner Fink

Hmmm ... can not reproduce, just installed noto-sans-cjk-fonts and (as expanded
by zypper) also noto-sans-jp-bold-fonts noto-sans-jp-fonts
noto-sans-jp-regular-fonts noto-sans-kr-bold-fonts noto-sans-kr-fonts
noto-sans-kr-regular-fonts noto-sans-sc-bold-fonts noto-sans-sc-fonts
noto-sans-sc-regular-fonts noto-sans-tc-bold-fonts noto-sans-tc-fonts
noto-sans-tc-regular-fonts

and started xfig ... it starts and stays here ...

Please show you locale settings (output of the program locale) as well as your
~/.fonts.conf if you have one
