Telegraf service crashes with "Panic: Runtime Error: Slice bounds out of range"

[deveth0]

Bug report

System info: [Include InfluxDB version, operating system name, and other relevant details]
Debian 8 running Telegraf 1.2.0-1 from repos.influxdata.com

Steps to reproduce:

Expected behavior:
Telegraf does not crash

Actual behavior:
After some time the telegraf service crashes with the attached error. I'm not sure if this is related to the snmp errors we see but I'd expect that telegraf just ignores those.

Additional info:
