Looks like the spinner.gif and spinnerstopped.png you've commited to SVN are html pages.
Trac is really confusing regarding the image links. For example, this is a link to a html page containing the description of the item http://trac.turbogears.org/turbogears/attachment/ticket/274/spinnerstopped.png And this is a link to the real image http://trac.turbogears.org/turbogears/attachment/ticket/274/spinnerstopped.png?format=raw -- Claudio
