I'm at the same time staring at this bit in pixbufcache.bbclass:

gdkpixbuf_complete() {
GDK_PIXBUF_FATAL_LOADER=1
${STAGING_LIBDIR_NATIVE}/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders
--update-cache || exit 1
}

DEPENDS_append_class-native = " gdk-pixbuf-native"
SYSROOT_PREPROCESS_FUNCS_append_class-native = " pixbufcache_sstate_postinst"

# See base.bbclass for the other half of this
pixbufcache_sstate_postinst() {
        mkdir -p ${SYSROOT_DESTDIR}${bindir}
        dest=${SYSROOT_DESTDIR}${bindir}/postinst-${PN}
        echo '#!/bin/sh' > $dest
        echo "${gdkpixbuf_complete}" >> $dest
        chmod 0755 $dest
}

It's all written for -native, yet the script that fails, resides in
tmp/sysroots/qemux86-64/usr/bin/postinst-gdk-pixbuf-native (e.g. the
target sysroot which is racing with the native one). Why is it even
there?
I haven't written this code :) and haven't really seen it before, but
this might be a lead.
