I wonder why g_strdup_printf() isn't used instead. Would allow ignoring
PATH_MAX.

I guess it is because it is easier. With g_strdup_printf() one would
have to take care about freeing memory. This is not a case with having
filename as an atomatic variable.

Patch looks fine, but we don't use Signed-off-by in userspace tree.
