[Bug 914746] Re: cacti SNMP verbose query PHP error

[Stéphane Graber]

I haven't looked at the patch, though there are a few more information that are needed before considering an SRU here:
 - Please add a [rational], [test case] and [regression potential] section to the bug description (https://wiki.ubuntu.com/StableReleaseUpdates)
 - What version was this bug fixed in? Apparently most people seem affected by this on 10.04, but any intermediary supported release should also be fixed to prevent regressions on upgrade from 10.04.

Marking the bug Incomplete for now, please change it back to New when
these information are added.

** Changed in: cacti (Ubuntu Lucid)
       Status: New => Incomplete

Bug description:
  when adding an SNMP - Interface statistics data query, and clicking on
  the 'verbose list' link, I get a 500 internal error, and the following
  line in the apache log file:

  PHP Fatal error:  Cannot use string offset as an array in
  /usr/share/cacti/site/lib/data_query.php on line 183, referer:
  http://localhost/cacti/host.php?action=edit&id=1

  this prevents me from having network interface statistics followed by
  cacti.
