Comment (by maehne):

 I have tried to upgrade the Portfile (see attached
 {{{Portfile.20170716}}}). However, I am observing graphical problems in
 the GTK3-based GUI: All icons on the buttons are missing if only {{{port
 :bicolor-icon-theme}}} is installed. Installing {{{gnome-themes-
 standard}}} improves the situation somewhat, but the GUI is still ugly due
 to the missing icons. Interestingly, the {{{+gtk2}}} variant of the
 previous version 20160605 didn't have that problem. However, I also
 observed the same missing icons problem with the {{{+gtk3}}} variant. See
 the attached screenshots for an illustration of the problem.

 I have contacted upstream regarding the problem. However, if I remember
 correctly, he is using Linux rather than macOS. Therefore, it might be
 difficult for him to reproduce the problem. There is also the possibility
 that it is a problem proper to the MacPorts' version of GTK3. Any ideas? I
 am lacking experience with GTK3 GUI programming and don't have much time
 to dig into this. So any help would be welcome!
