Bug#858279: kdialog: icons too small on HiDPI display

[solitone <solitone@mail.com>]

Package: kde-baseapps-bin
Version: 4:16.08.3-1
Severity: minor

Dear Maintainer,

the Save and Cancel icons in KDialog are too small on a HiDPI 
display, like my MacBookPro 12,1 retina display.

This happens both when saving something from e.g. Chrome or Gimp, 
or when I run kdialog from the command line like in the following 
example:

solitone@alan:~$ kdialog --getsavefilename /tmp

This likely depends on release 16.08 provided in stretch, which is 
based on Qt 4.8.7 and KDE Development Platform 4.14.26.  Qt 4.8.x 
does not support HiDPI very well.

An upgrade to kdialog 16.12 (based on Qt 5 and kde-frameworks 5) 
would therefore be desiderable.

Thanks & Regards,
  Davide
