Typo3 - when enabling debug mode Install Tool Configuration Presets broken for image handling settings

If "Configuration Presets" ist set to Debug the "Configuration Presets" is broken. It returns an AJAX Error:

Core: Error handler (BE): PHP Warning: file_exists(): open_basedir restriction in effect. File(/opt/local/bin/identify) is not within the allowed path(s): (/home/users/schlossblick/www:/home/users/website/files:/home/users/website/tmp:/usr/local/bin:/usr/bin) in /home/users/website/files/website.de/typo3_src-13.4.14/typo3/sysext/install/Classes/Configuration/Image/ImageMagick6Preset.php line 79

 

Temporär solution set "Configure Installation-Wide Options" -> [GFX][processor_path] from /usr/bin/ to /usr/bin. Then "Configuration Presets" load without error. Set Debug mode to off an then you can use "Configuration Presets" again to switch preset between GraphicsMagick and ImageMagick6.
