Handling of images with spaces in the names

I can't seem to find a solution to this problem, so please forgive me if this is a double report.

I'm using Insert Views to create a Simplenews node, and sending that out through mimemail. When images are embedded that have a space in the name, I'm getting a %20%20 in the url rather than a single %20 to denote the space. Prior to sending it looks great, after receiving the email, it's a broken image.

http://www.talksv.com/sites/default/files/imagecache/Thumbnail/Control%2... is what the url in the email looks like.

http://www.talksv.com/sites/default/files/imagecache/Thumbnail/Control%2... is the actual url, and the way it appears prior to sending.

I've been searching for two days for the answer to this one, but I can't seem to find anything helpful. Anyone have any ideas?
