[TYPO3-piwik] Errors in localconf.php

[Stefano Kowalke]

Hey,

i got errors when i activate the BE-Module of EXT:piwikintegration
because of these two entries in the localconf.php:

// Display the navigation titles instead of the title in the backend
pagetree
t3lib_extMgm::addUserTSConfig('options.pageTree.showNavTitle = 1');

// Inherit the realurl pathsegment to the subpages
$TYPO3_CONF_VARS['FE']['addRootLineFields'] .=
',tx_realurl_pathsegment,alias,nav_title,title';

Maybe this two lines are not very common, but important for this
installation, so I can't remove it.

My question:
Why and where EXT:piwikintegration excute localconf.php?
