Comment (by tgreenwood):

 Here are some of the people who have seen this from what I've found. Some
 have recompiled to fix this.  Two of the causes seem to correlate with
 what I've seen (Cisco and CounterPath equipment) - interestingly one
 person had seen x264 get to 17.

 I will capture a stream and create a patch file when I get the time.
 Thank you for your help.
