I'm using Symfony 2.8 and PHP Fatal error occurs very rarely when I do assetic:dump / cache:warmup as below.(also on Symfony 2.7)
`
PHP Fatal error: Call to a member function removeChild() on null in .../symfony/symfony/src/Symfony/Component/DependencyInjection/Loader/XmlFileLoader.php on line 350
`
It does occur very rarely. Also, after several retries, it works fine.
The xml file which triggers error is as below(both version) and I didn't modify anything.
https://github.com/symfony/swiftmailer-bundle/blob/v2.3.8/Resources/config/swiftmailer.xml
https://github.com/symfony/swiftmailer-bundle/blob/v2.6.7/Resources/config/swiftmailer.xml
Once more, error occurs so randomly. So, I can't be sure in what situation it occurs. But this modification does fix the problem and no side effect.
