Gtk Configuration is doesn't display real current configuration status after upgrade from Precise to Quantal

First of all, there was no kde-gtk-config in Ubuntu Precise. This package was firstly added in Ubuntu Quantal. Another package (kcm-gtk) was in Ubuntu Precise instead.

> Icon checkboxes is not set, Icon theme is not selected, GTK style toolbar is not selected

There were no such options in kcm-gtk 2:0.5.3-1ubuntu3. They are new and they use default values at first launch.

> some random font (probably just first font from fonts list, sorted in alphabetical order) instead of used in Precise Ubuntu regular 9 font

Did you have the same ~/.gtkrc-2.0-kde4 and ~/.gtkrc-2.0 files before update? (See LP: #1051630)

> Icon theme is not selected

At least this will be solved when kde-gtk-config 3:2.1-1ubuntu1 is uploaded. (See LP: #1047387)

> They are new and they use default values at first launch.
First launch of Gtk Configuration? But in fact GTK applications use for example show icons in GTK buttons and menus, but this fact doesn't reflected in default values of Gtk Configuration (no checkboxes "Show Icons in GTK Buttons" and "Show Icons in GTK Menus").

Yes, but this files contain information only about theme, not about font. (This issue tested in VM on clear Kubuntu 12.04.1 installation upgraded to Kubuntu 12.10 Beta 2, so you may easily reproduce it.)

Thank you for link! I hope this package will be updated.

P.S. There is same issue on clear Kubuntu 12.10 Beta 2 installation too.

Yes.

I will ask upstream if system settings can be checked at first launch.

> Yes, but this files contain information only about theme, not about font.

Maybe you are right. I was not the maintainer of kcm-gtk and I do not remember where it stores its font settings.

But kde-gtk-config stores it in ~/.gtkrc-2.0-kde4. For example, my current settings:

$ cat ~/.gtkrc-2.0-kde4
# File created by KDE Gtk Config
# Configs for GTK2 programs

include "/usr/share/themes/QtCurve/gtk-2.0/gtkrc"
style "user-font"
{
        font_name="Sans Serif"
}
widget_class "*" style "user-font"
gtk-font-name="Sans Serif 10"
gtk-theme-name="QtCurve"
gtk-icon-theme-name="oxygen"
gtk-fallback-icon-theme="oxygen"
gtk-toolbar-style=GTK_TOOLBAR_ICONS
gtk-menu-images=1
gtk-button-images=1

Developer replied. Quotation:
> They are already being checked (it uses the Qt/KDE settings as default).

Then why Gtk Configuration de facto doesn't display currently used configuration in case of Kubuntu?

This bug was fixed in the package kde-gtk-config - 3:2.1-1ubuntu1

---------------
kde-gtk-config (3:2.1-1ubuntu1) quantal; urgency=low

  * Merge with Debian for bugfix release LP: #1047387
    remaining changes:
   - Remove build dependency on libgtk2.0-dev and libgtk-3-dev.
   - Add patch debian/patches/kubuntu_01_no_gtk.diff
  * Fixes ability to scan for gtk settings LP: #1058464

kde-gtk-config (3:2.1-1) unstable; urgency=low

  * Update to stable release 2.1.
  * Deleted file debian/patches/fix-build-on-kfreebsd-and-hurd-i386:
    accepted in upstream.
  * Added file debian/patches/fix-loading-icons:
    without this patch KDE-GTK-Config module scans ./ directory if option
    gtk-icon-theme-name or option gtk-fallback-icon-theme is empty or invalid,
    now first element from the list of found icon themes is used.

#6 what do you mean by "Gtk Configuration de facto doesn't display currently used configuration"?

Right now, when you press the "Default" button, the dialog is sync'ed with the used settings on your system.

I check updated package: unfortunately there is still problem with font. Do I need fill new bugreport or reopen this one?

> what do you mean by "Gtk Configuration de facto doesn't display currently used configuration"?
Exactly that. User expect to see currently used configuration when he open some settings module.

> Right now, when you press the "Default" button, the dialog is sync'ed with the used settings on your system.
Everything else (including need of additional action, like click on "Default" button to see currently used settings) is unexpected UI behavior.
