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

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? -- phani.
