This bug relates to the common file-open dialog. As a sample, I'm using the one that appears in the control center, when loading multiple background images.
Open Control Center, go to desktop background->background picture (or something like that, I have the GErman version...) and hit the button 'setup for multiple pictures'. There, hit the 'add' button to get the file open dialog. Now navigate to a directory with lots of files - enough so that you have multiple columns. Files displayed will look like this:

 a_file   f_file   k_file
 b_file   g_file   ...
 c_file   h_file
 d_file   i_file
 e_file   j_file

now click on 'a_file', hold down shift, and click on 'h_file'. What is selected will be (selected files marked with a '*')

*a_file  *f_file k_file
*b_file  *g_file ...
*c_file  *h_file
 d_file   i_file
 e_file   j_file

But that is quite contradicting to how files are displayed! Holding down shift while selecting multiple files means 'select everything up to here'. Since files are sorted in columns, what should be selected should be rather all files up to 'h_file', which would be:

*a_file  *f_file k_file
*b_file  *g_file ...
*c_file  *h_file
*d_file   i_file
*e_file   j_file
