[pcp] pminfo -t aborts pmcd (#30)

[ABC <notifications@xxxxxxxxxx>]

Excuse me, but when first and simplest command from manual crashes, it's a bit weird for 20 year old software.

apt-get install pcp on Ubuntu 14.04.2 LTS, pcp package version is 3.8.12ubuntu1

root@n:~# ps axu|grep pmcd
pcp      15018  0.0  0.5  25580 12148 ?        Ssl  10:39   0:00 /usr/lib/pcp/bin/pmcd
root@n:~# pminfo -t
[... lots of output skipped ...]
root@n:~# pminfo -t
pminfo: Cannot connect to PMCD on host "local:": Connection refused
root@n:~# ps axu|grep pmcd

When I do service pcp restart pminfo -t works again, once more. Also, pminfo w/o -t doesn't abort pmcd.
