WSOD with Phone + Entity Translation

Hi cdale,
Flushing caches before or even disabling caches didn't work.
Logs shows always the same error:
PHP Fatal error: Cannot access empty property in /all/modules/entity_translation/includes/translation.handler.inc on line 728

line 728: $this->entity->{$translations_key} = self::emptyTranslations();

 /**
   * @see EntityTranslationHandlerInterface::setEntity()
   */
  public function setEntity($entity) {
    $this->entity = $entity;

    // Ensure translations data is populated.
    $translations_key = $this->getTranslationsKey();
    if (!isset($this->entity->{$translations_key})) {
      $this->entity->{$translations_key} = self::emptyTranslations();
    }

    // Update bundle and entity id properties.
    list($this->entityId, , $this->bundle) = entity_extract_ids($this->entityType, $this->entity);
  }

Thanks!

I just bumped again today with this, impossible to have phone 7.x-2 dev and entity translation in the same installation.
Error WOSD (sometimes not inmediately but trying to add a new field) and as seen on drush:
WD php: Exception: Cannot initialize entity translation path variables (invalid path scheme). in EntityTranslationDefaultHandler->initPathVariables() (line 1449 of [error]
/var/www/mysite/sites/all/modules/entity_translation/includes/translation.handler.inc).
Drush command terminated abnormally due to an unrecoverable error. [error]
Exception: Cannot initialize entity translation path variables (invalid path scheme). in EntityTranslationDefaultHandler->initPathVariables() (line 1449 of /var/www/mysite/sites/all/modules/entity_translation/includes/translation.handler.inc).

Any tips ?
Thanks.

Today's test has been done with Last packaged version: 7.x-1.0-beta2+26-dev - Last updated: March 23, 2013 - 00:54
No luck :(
