Hey,

I should have looked more in depth at these commits earlier, sorry for the
late feedback ;)

osinfo_loader_process_default_path() looks into
$XDG_CONFIG_DIR/libosinfo/db so end users can override it, but users of the
library may indeed also want to be able to override it.

I'm not sure we want to error out there, see
http://git.fedorahosted.org/cgit/libosinfo.git/commit/?id=dbde512c3a64640d61fa5e7f801050e248f60c98
for my reasoning (and you can try a "mkdir -p ~/.config/libosinfo/db &&
echo '<bad' >~/.config/libosinfo/db/broken.xml" to get into a 'bad'
situation).
