QT4 Trolltech.conf settings lost after reboot

[mrvanes]

Since the update to Kubuntu 17.04 / plasma 5.9.4 all qt4 based applications (e.g. KeePassX) render using wrong font instead of my personal configured font. When I run qtconfig-qt4 (4.8.7), change font and click 'save', a fresh .config/Trolltech.conf is saved, contains the correct font config and all qt4 applications now show correct font. These settings however do not survive a reboot although Trolltech.conf exists and contains correct settings.

Status changed to 'Confirmed' because the bug affects multiple users.

Same.
After saving the qtconfig settings and reboot, there are two lines "fonts=" appears in ~/.config/Trolltech.conf

#after reboot
$ cat ~/.config/Trolltech.conf | grep font=
font="Ubuntu,8,-1,5,50,0,0,0,0,0"
font="Sans Serif,9,-1,5,50,0,0,0,0,0"

#after manual qtconfig saving
$ cat ~/.config/Trolltech.conf | grep font=
font="Ubuntu,8,-1,5,50,0,0,0,0,0"

Fixed, for me, in (K)Ubuntu 17.10, Artful.
libqt4 4.8.7
libqt5 5.9.1

Yes, in Artful all is ok.
