[Serusers] Strange Via parsing error....

[sip]

I'm getting an odd Via parsing error from SER 0.9.6: 

Feb 23 16:52:49 death ser[17389]: error: parse_via_param 
Feb 23 16:52:49 death ser[17389]: ERROR: parse_via on: <sip/2.0/udp

When I look at the packet, it looks like the actual SIP data is somehow
getting garbled... with odd characters showing up in the middle of headers, etc. 

Any idea what might cause this?

As you can see... things like REGISTEl,  Max Forward2a:   Expire1k: 

All these things look garbled.  Would this be a transmission error of some
kind (the garbled headers are identical for each submitted packet, though, so
it seems unlikely) ?
