Observed on mediawiki.org during page creation on 1.20wmf3:

PHP fatal error in /usr/local/apache/common-local/php-1.20wmf3/extensions/Translate/tag/TranslatablePage.php line 108:
Argument 1 passed to TranslatablePage::newFromTitle() must be an instance of Title, null given, called in /usr/local/apache/common-local/php-1.20wmf3/extensions/Translate/tag/PageTranslationHooks.php on line 414 and defined

Does not happen on test2 or translatewiki.net.

Solution for now was to return true at the top of updateTranstagOnNullRevisions().
