TYPO3 Core

When trying to add a new task from within 'Scheduled Task' or 'Information' area page reloads but no new task appears in list.

In protocol the following entries are logged:
Core: Error handler (BE): PHP Warning: in_array() expects parameter 2 to be array, boolean given in /var/www/typo3_src-4.5.10/typo3/sysext/extbase/Classes/Object/Container/Container.php line 259
. . . ! . Core: Error handler (BE): PHP Warning: class_implements(): Class Tx_Extbase_MVC_CLI_CommandManager does not exist and could not be loaded in /var/www/typo3_src-4.5.10/typo3/sysext/extbase/Classes/Object/Container/Container.php line 259

As I found a previous bug here (#32961) concerning a similar failure I tried to delete some extensions, especialy one wich had been changed (set up a newer version of solr from svn instead of ter). But it did'n have any effect.

On initial setup the extension seemed to be working properly. At least I was able to add a task (Convert user passwords saltedpasswords). This task could be edited too while adding new tasks was not possible.

Here is a list of extensions providing tasks in 'Information' area:
- em: Update Extension List
- reports: System Status Update
- workspaces: Workspaces auto-publication
- linkvalidator: Convert user passwords to salted hashes, Linkvalidator
- scheduler: Scheduler test task, Scheduler sleep task, Caching framework garbage collection
- fed: Extbase CommandController Task
