Comment 7 Jeff Layton 2014-04-16 12:58:14 UTC 
Ok, I merged Sebastian's patch (with a small modification).

I've proposed a couple of other patches to help fix up the error handling, including the case where the buffer would have been overrun. Assuming no one objects, I'll merge them in the next few days and we can get this package built for f20:
