Any GTK+ apps - segmentation fault [Solved]

[cmost]

Today I stupidly upgraded my oxygen-gtk, which I employ for unified appearance for my KDE 4.7 desktop. After compiling and installing the latest version just released days ago, I started receiving the following error for ANY GTK application (using firefox as the example.)

Code: Select all

cmost@cmost-sabayon64 ~ $ firefox

(firefox-bin:17550): Gtk-CRITICAL **: IA__gtk_settings_set_long_property: assertion `GTK_SETTINGS (settings)' failed

(firefox-bin:17550): Gtk-CRITICAL **: IA__gtk_settings_set_long_property: assertion `GTK_SETTINGS (settings)' failed

(firefox-bin:17550): Gtk-CRITICAL **: IA__gtk_settings_set_string_property: assertion `GTK_SETTINGS (settings)' failed

(firefox-bin:17550): Gtk-CRITICAL **: IA__gtk_icon_theme_get_for_screen: assertion `GDK_IS_SCREEN (screen)' failed

(firefox-bin:17550): Gtk-CRITICAL **: IA__gtk_icon_theme_get_search_path: assertion `GTK_IS_ICON_THEME (icon_theme)' failed
Segmentation fault


My system is fully up-to-date (Limbo enabled, Gnome 3.02 libraries, etc.) I did some research online and discovered that oxygen-gtk does not support Gnome 3 libraries and the workaround was to remove it and choose another theme for GTK apps. Trying to do a make uninstall on the oxygen-gtk failed for some reason:

Code: Select all

cmost@cmost-sabayon64 ~/Downloads/Oxygen-gtk/oxygen-gtk/build $ sudo make uninstall
Password:
make: *** No rule to make target `uninstall'.  Stop.


I tried choosing a different GTK theme (QTcurve) in KDE control center --> Appearance --> GTK apps but this fails to fix the above segmentation fault. Does anyone have any idea how to get things back to normal? I think I'm going to have to manually remove the rogue oxygen-gtk program by deleting all its files, but I want to make sure this is the best course of action before proceeding. Any help greatly appreciated.

Problem solved (sort of...)

I realized that oxygen-gtk does not support GTK3. There's an early alpha of oxygen-gtk that does support GTK3, which I downloaded with Git with the following command:

Code: Select all

git clone -b gtk3 git://anongit.kde.org/oxygen-gtk


After compiling and installing this version, I did the ffollowing to link the new theme engine to GTK3 apps.

Code: Select all

sudo ln -s /usr/share/themes/oxygen-gtk/gtk-3.0 ~/.config/gtk-3.0


After that, MOST of my GTK apps work as expected. Of course they're using the ugly GTK3 fonts and Firefox doesn't show folders, even after I did: (Where 'Prefered Gnome Icon Theme = whatever icon theme you want Gnome 3 to use...)

Code: Select all

gsettings set org.gnome.desktop.interface icon-theme 'Preferred Gnome Icon Theme'


Audacious still won't work!!! I get a string of similar errors when trying to launch it from the command line. I can use Amarok in the meantime. Ugh!

But, I can live with the result. I miss Gnome 2.32...
