encrypted ipc QA failures

[Ken McDonell <kenj@xxxxxxxxxxxxxxxx>]

I'm seeing this

16c16
< pminfo: Cannot connect to PMCD on host "HOST": Peer's certificate has 
an invalid signature.
---
> pminfo: Cannot connect to PMCD on host "HOST": Unknown code ___f 10

for 712 713 and 714 on vm11 PCP 3.7.1 i586 Debian 6.0.7
(sometimes the line ends in ___f 13)

Does this look familiar to anyone ... is it some sort of QA setup I'm 
missing or a PCP problem?
