Description

Title::newFromText(':') results in an apparently valid Title object that stringifies to "".

It seems to be caused by the following logic in Title#secureAndSplit:

if ( $dbkey == '' && $this->mInterwiki == '' && $this->mNamespace != NS_MAIN ) {
return false;
}

The last check for namespace != NS_MAIN explicitly makes it so that 'Talk:' is considered invalid, but ':' is excluded for some reason.
