The spinner images are now included in CVS and the 2.13.7 release.

strange!!! this problems happen in gnome-icon-theme 2.13.7, icon-naming-utils-0.6.7.

$gtk-update-icon-cache --quiet /usr/share/icons/hicolor

this problem is fixed.

index.theme has not been updated to include the animation directories, so it is still broken in 2.13.7

Using latest (updated 5 minutes ago) g-i-t and i-n-u there is another issue: bot gnome-spinner and gnome-spinner-rest are loaded only at 16x16 size.

index.theme seems good... strange.

The strace output loading epiphany

It seems that 24x24 is ignored only loading spinner. Maybe it's a bug in spinner code?

No. The problem is that a size of -1 is being requested. This means that the smallest size available will get used, as it is the closest match to -1. This means that the code needs to be fixed to request proper sizes based on the size of the widget that is containing the image, rather than using -1. I'm surprised this hasn't come up until now, really.

Bug for nautilus: # 330417
Bug for epiphany: # 330415

Well, in the old icon theme, the spinner was only available at a 'native' size and the spinner code is doing the scaling to use the images at the size the spinner wants to have (we support all GtkIconSizes, and epiphany uses it in GTK_ICON_SIZE_MENU, BUTTON, LARGE_TOOLBAR, and the old native 36x36 size.)

This bug was fixed in gnome-icon-theme-2.14.0.

Please do not close bugs against g-i-t as "fixed in 2.14.0", as the bugs need to remain open for 2.15. 2.14.0 is an old revision of git, to satisfy needs for GNOME 2.14.0 and restructuring will continue on HEAD for 2.15/2.16.

OK. This icon is in HEAD and available in 16, 22, 24, and 48 pixel sizes. A 32x32 frame animation will be available soon as well. I'm closing this as fixed. As far as the spinner code in Epiphany and Nautilus go, they need to be fixed to look up the correct size for the icon, and not -1, then doing scaling.
