Not sure if this is relevant, but since you mention you're on an old release I 
recall fixing something relating to this a while back:

  http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=68fbbd1008a76d78c7cef141dc06696d27fe2d0c

The first release to have this fix in it was 1.6 (daisy).

Cheers,
Paul
