Public bug reported:

Hello!

onDeleteClick in images/lib/mediaitem does not delete the images
accurately. Just try to delete more than one image at one time. It will
not work (unless you know what is going wrong). It depends in what
sequence you select the images.

The Problem is, that
"ListView.selectedIndexes()" does not sort anything (rather saves everything in the order we pass it on = the sequence we click the images). [1]

If I would do this:

    for item in items:
        log.debug(u'Row: %s' % item.row())

My log file will show something like this:
... Row: 8
... Row: 11
... Row: 1
... Row: 9
........

Until this point everything is alright, but when we go on with
"self.ListView.takeItem(item.row())" we start deleting things (-> the
rows start changing (in this case row 11 and row 9 are affected by this,
because we deleted row 8)).

To solve this problem we need to sort the array (by the row numbers) or
something similar. You can check this by selecting some images in the
media manager starting from the bottom. This will work, because "items"
is now coincidentally in the right order.

Cheers
