[Semediawiki-user] Semantic Drilldown in Semantic Bundle throwing Installation Error

[Pavey, D. <David.Pavey@CommerceBank.com>]

Trying to install a wiki into a pristine environment and I get an
exception when generating the site:

Including extensions...
( ! ) Fatal error: Unsupported operand types in

on line 144

I've started with MW 1.17.0 and uncompressed the semantic-bundle version
2011-08-04.20110804 into the extensions directory. From there I brought
up the home page and clicked through to do the install. After completing
the forms and confirming the install, the system quickly gets to the
dump listed above.

Seems to be complaining about extending the
$smwgNamespacesWithSemanticLinks array (line 140-144 in
SematicDrilldown.php).

Am I missing a step somewhere? I'm using the following WAMP environment:
