Import questions hotpot

In version 1.9.6 if you try to import a *.jqz a Quiz only shows "Parsing questions from import file." It is a bug and does not give you any further information. In the 1.9.5 does not happen. I looked and I have observed comes from changes in "question/format/hotpot/format.php". More specifically the functions that have been exported to "/mod/hotpot/lib.php". If those functions that have been exported, keep in format.php, the imports of the hotpot is working properly.

Sorry for my English.
