TYPO3 Core

Running the environment check without having the function imageftbbox enabled an Exception occurs that is even suppressed by using @imageftbbox. Therefore the whole page is just white.

Removing the @, the following Exception is shown:

 Fatal error: Call to undefined function TYPO3\CMS\Install\SystemEnvironment\imageftbbox() in /vagrant/src/typo3_src/typo3/sysext/install/Classes/SystemEnvironment/Check.php on line 1073

A solution would be to check if the method is available via function_exists.

I could also provide a patch but I am unsure about the message that should be displayed to the user.
