Title:
  Mediascanner2 crash on model change with header in listview

Status in mediascanner2 package in Ubuntu:
  Expired

Bug description:
  Hi,

  I am experiencing a crash of mediascanner2 when the model changes (eg
  artist for the AlbumsModel). It appears that I have to have both a
  delegate and header set in the listview otherwise the error doesn't
  occur. I have an example [0] which crashes when I select an artist on
  the left and it attempts to show the albums for that artist on the
  right.

  I have also run this inside GDB [1].

  This is was found when migrating the music-app from sheets to pages
  (as sheets are deprecated). We believe it did not happen before
  because the sheet was being (de)constructed each time, therefore the
  model wasn't being changed. Where as a page is just being push/pop'd
  to and from a pagestack. This issue is now the only thing blocking
  music-app from migrating to pages.
