Thread:Extension talk:Maps/Unable to call MapsDisplayMap::initialize()

Trying to install Maps on PHP 5.2.0 gives the following error:

Warning: call_user_func(MapsDisplayMap::initialize) [function.call-user-func]: Unable to call MapsDisplayMap::initialize in .../extensions/Maps/Features/Maps_ParserFunctions.php on line 38 Warning: call_user_func(MapsDisplayPoint::initialize) [function.call-user-func]: Unable to call MapsDisplayPoint::initialize in .../extensions/Maps/Features/Maps_ParserFunctions.php on line 38

This is due to the lines 37-39 (in 0.6 rc3, r67115): which will result in calls like  which is a format supported by PHP 5.2.3+ only (as opposed to   which works in PHP 5.*).

Quick workaround:
