I use KDE Apps 15.12.3, KF 5.22.0 and Plasma 5.6.4, especially Breeze GTK 5.6.5. If I start an application that is based on GTK, e.g. Gimp, Firefox, the .xsession-error file is filled with error messages like Gtk-WARNING: Theme directory [...] of theme breeze has no size field More precisely there are Gtk-WARNING **: Theme directory actions/48 of theme breeze has no size field Gtk-WARNING **: Theme directory categories/16 of theme breeze has no size field Gtk-WARNING **: Theme directory categories/22 of theme breeze has no size field Gtk-WARNING **: Theme directory categories/48 of theme breeze has no size field Gtk-WARNING **: Theme directory devices/48 of theme breeze has no size field However, the particular directories depend on the specific GTK-based application. Gentoo Bug mainters ask me to report this bug upstream (Bug report at Gentoo: https://bugs.gentoo.org/show_bug.cgi?id=583898) Reproducible: Always Steps to Reproduce: 1. Use Breeze as a GTK theme 2. Start some GTK-based application 3. Look at ~/.xsession-error Actual Results: ~/.xsession-error is filled with errors about missing size information for icons from the Breeze theme Expected Results: No error messages.
Can't reproduce in: Plasma: 5.12.1 Apps: 17.12.2 Frameworks: 5.43.0 Qt: 5.10.1 Kernel: 4.14.20-2-MANJARO OS: Netrunner Rolling
Fixed now!
