Comment 1 Dario Massarin 2009-10-07 19:34:41 UTC 
SVN commit 1032383 by dario:

* get rid of the postDeletedEvent. Put instead a deinit() function in the Transfer class
* put a non virtual create() and destroy() function in the transfer class. These becomes
  so useful in doing some stuff like managing the scheduler when we are deleting a transfer
  or, for example, deinitializing the NepomukHandler
* In this way we can take the scheduler deinitialization stuff out of the Transfer class
  destructor. Should solve bug 209755.
