Corrupt VarBinds from SNMP.pm

Hello

I'm using SNMP.pm 5.0401 from Debian's release of 5.4.1 which is
5.4.1~dfsg-7.1.

Running the following code:

#!/usr/bin/perl -w

use strict;
use warnings;
use SNMP;

my $sess = new SNMP::Session( DestHost => 'localhost', Community => 'public', Version => 2 );

my @vbl;

push @vbl, [ 'sysUpTime', 0 ];
push @vbl, [ 'sysName', 0 ];
push @vbl, [ 'sysLocation', 0 ];
push @vbl, [ 'sysContact', 0 ];

my $varlist = new SNMP::VarList(@vbl);

$sess->get($varlist);

print "ERROR WAS: ".$sess->{'ErrorStr'}."\n";

foreach my $vb (@$varlist) {

print "0:".$vb->[0]."\n";
print "1:".$vb->[1]."\n";
print "2:".$vb->[2]."\n";
print "3:".$vb->[3]."\n";

}

....produces strange results:

ERROR WAS:
0:sysUpTimeInstance
1:
2:20887615
3:TICKS
0:sysName.0
1:
2:ysName.0nstance<HEX>
3:OCTETSTR
0:sysLocation.0
1:
2:ysLocation.0
3:OCTETSTR
0:sysContact.0
1:
2:ysContact.0nce<HEX>
3:OCTETSTR

<HEX> in this case is some random high-ASCII unprintable characters.

I can't figure out why this is happening. Using snmpget:

pwh@devil:/tmp$ snmpget localhost -c public -v 2c sysUpTime.0 sysName.0 sysLocation.0 sysContact.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (20896259) 2 days, 10:02:42.59
SNMPv2-MIB::sysName.0 = STRING: devil.noc.example.com
SNMPv2-MIB::sysLocation.0 = STRING: Datacentre 4
SNMPv2-MIB::sysContact.0 = STRING: Operations <operations@example.com>

Just getting sysUpTime in perl works fine, it's only when I try to get the
other OIDs that things go wrong.

Can anyone help me troubleshoot?

For the records: this seems to be a Debian bug introduced by a recent
bug fix attempt. The Debian package is about to be updated.

See http://bugs.debian.org/483588 for the details and progress.
