TYPO3 Core

Following situation:

1. $TYPO3_CONF_VARS['BE']['interfaces'] = 'backend,frontend'; is activated in localconf.php
2. Login directly to frontend. I will be redirected correctly and I see the admin panel.
3. Clicking on the "open TYPO3-Backend" a new window opens with my webpage again. I won't be redirected to the backend.

Reason:
in class.t3lib_befunc.php on line 4834 the function getBackendScript() - called in class.tslib_adminpanel.php on line 574 - will return '../.' in this case.

Possible solutions:
1. add backend.php manually in line 574 in class.tslib_adminpanel.php and remove the method getBackendScript()
2. add parameter 'backend' in line 574 when calling method getBackendScript(). ( t3lib_BEfunc::getBackendScript('backend') )

Cheers,

Mischa.
