Ahh, I knew I should have checked that.
Still, the (travis build) error seems to come from URLAliasService attempting to use ```$spiUrlAlias->pathData```
(see https://github.com/joaoinacio/ezpublish-kernel/blob/98a0bce6b430aa2decc86cec7043ade028888fb3/eZ/Publish/Core/Repository/URLAliasService.php#L427 )
Unfortunately I can't seem to cause tests to fail locally...
