/usr/share/themes/NOX/gtk-2.0/gtkrc:233 Murrine configuration option 'gradients' is no longer supported and will be ignored x11-themes/murrine-themes - 0.98.0 version x11-themes/gtk-engines-murrine - 0.98.0 version
Please report this with upstream. I don't use GNOME 2 anymore and hence can't reproduce this.
Seems easy to patch: http://web.archiveorange.com/archive/v/LLXmLJLul0sJ2Hj4o5Rh https://bugs.launchpad.net/ubuntu/+source/human-theme/+bug/345417 http://www.khattam.info/solved-murrine-configuration-option-scrollbar_color-gradients-is-no-longer-supported-and-will-be-ignored-2010-02-11.html Apparently, there are 4 offending options: the unsupported "scrollbar_color" and "gradients" (only for gtk+-2?) and the deprecated "hilight_ratio" and "highlight_ratio", for which "highlight_shade" needs to be used instead. Apparently, "lightborder_ratio" can be changed to "lightborder_shade", too. My setup: gtk+-2.24.4 (introspection, xinerama) gtk-engines-murrine-0.98.1.1 (themes) murrine-themes-0.98.0
Fixed in 0.98.11.
