I found today the following in my debug log corresponding to my error.

2013-12-24T11:43:11+05:30 DEBUG: Variable information:
object(Horde_Support_ObjectStub)#169 (1) {
  ["_data":protected]=>
  object(stdClass)#172 (0) {
  }
}

If you feel, if this is really the correct debug log extract, I will file a
bug report.
