Comment 2 for bug 1182766

Thanks a lot for testing and for reporting this bug. This is really helpful.

For those buttons, we're using these standard GNOME symbolic icons:

- preferences-color-symbolic (/usr/share/icons/gnome/scalable/apps/preferences-color-symbolic.svg)
- edit-select-all-symbolic (/usr/share/icons/gnome/scalable/actions/edit-select-all-symbolic.svg)

It seems these were introduced in Ubuntu 12.10 [1] and are not available in Ubuntu 12.04.

We'll need to ship them in the Ubuntu 12.04 package.
