Bug#933001: returns 1 to plymouth initramfs hook, breaks initramfs creation

[Eduard Bloch]

Package: fontconfig
Version: 2.13.1-2
Severity: grave

After recent upgrades, initramfs update fails here. When I patch
/usr/share/initramfs-tools/hooks/plymouth with "set -x", this is what we
get. And this error handling = NOT helpfull.

E: /usr/share/initramfs-tools/hooks/plymouth failed with return 1.

Ok, trying more verbosity, still does not work. I expect
"--really-force" to fix everything, but it doesn't.

And now? The used font does exist!
