Hi Mark,
Mark Reynolds <mareynol(a)redhat.com>
We actually just fixed this on Friday via Ticket 305. Rich would
know
more about the next release that would contain this fix.
This is it
https://fedorahosted.org/389/ticket/305
The stuff is cos-related, and I saw the patch.
The "guilty" lines are moved... Can I just apply that patch or do I have to
checkout the whole new tree?
Peace,
R.
Regards,
Mark
