Title:
  Profile view, Edit: freeze of the UI when adding the external video
  file block using a wrongly encoded L10N

Status in Mahara ePortfolio:
  Fix Released

Bug description:
  Mahara 1.2.2 (vanilla)
  LAMP, PHP 5.2.12
  MySQL
  Integrated with Moodle, SSO IN (Moodle > Mahara)

  It seems just related toa  missing configuration parameter,
  ''videoid''; is it a bug or an error/missing done during the
  installation? IMHO no reason for the JSON encode error since no data
  has been passed yet and no chance at all to break any enconding
  sequence.

  Find below the complete log around the action described in the summary:
