@walterbender could you test if this breaks anything on fedora 19?

[samdroid-apps]

@walterbender just tested and it didn't seem to break

[godiard]

@samdroid-apps. should we keep the old rule for backward compatibility? Was tested on F18?

[samdroid-apps]

The old rule seems to break the newer versions.

It was not tested on F18... But do we still support that?

[quozl]

Let me know when you drop support for Fedora 18 and I'll fork all the repositories. ;-)

@samdroid-apps yeah, we still support it... a lot of users still run Sugar on top of fc18.

[samdroid-apps]

OK.

Would somebody be able to test on f18; I do not have access to an
installation?

Sure, please check my test method:

• apply the patch by hand to /usr/share/themes/sugar-{72,100}/gtk-3.0/gtk-widgets.css
• restart desktop,
• verify background in Log Files widget.

This is what it looks like on Fedora 18:

So you will probably have to write a conditional wrapper in the .css.em files, so use GTK_VERSION, discovered by configure.ac, substituted in gtk3/theme/Makefile.am. Let me know if you have any questions on that. GNU autotools for the win.

Replacing...
