A crash occurs when selecting thumbnials with ctrl-clicking them and then dragging the selection to new location.

Reproducible: Always

Steps to Reproduce:
- view thumbnails
- select one thumbnail
- select the previous thumbnail while pressing ctrl key
- grab either of the selected images and drag it to different location
- answer yes if you are prompted whether you really want to do this

Actual Results:  
crash

Expected Results:  
All selected items to be moved to selected location without crashes (note that removing the Q_ASSERT prevents the crash but skip rearranging of some images)

This functionality expects the selection to be sorted. However, no sorting occurs when selecting individual images (the Qt documentation even states that the selection is not sorted). Thus the whole rearrangement is faulty if the selection happens to contain unordered items. And a Q_ASSERT ensures a crash.

Buggy code is in file XMLDB/Database.cpp and function
DB::ImageInfoList XMLDB::Database::takeImagesFromSelection
