[arch-general] error during update of qt4 and qt5

[phani]

pacman wanted to update some qt4 and qt5 packages, but this didn't work  
because of the following error:

error: failed to commit transaction (conflicting files)
/usr/share/applications/assistant.desktop exists in both 'qt4' and  
'qt5-tools'
/usr/share/applications/designer.desktop exists in both 'qt4' and  
'qt5-tools'
/usr/share/applications/linguist.desktop exists in both 'qt4' and  
'qt5-tools'

seems both qt versions are trying to provide .desktop files with the same  
name. what to do about this?
