FLOW3's var_dump() still chokes on Doctrine collections
The patch provided with #37481 didn't solve the issue unfortunately.
Now, if you debug entities with properties of type
\Doctrine\Common\Collections\Collection the debugger throws an exception because it tries to cast an array to string.
The reason is, that
\Doctrine\Common\Util\Debug::export() returns an
stdClass while we expect a string.
