getimagesize and filesize error?

When trying to view thumbs in a view I get broken links (even though the image is actually there.) Then when I edit the view, I get this error?

warning: getimagesize(imagecache/thumb/files/imagename.jpg) [function.getimagesize]: failed to open stream: No such file or directory in [base url]/sites/all/modules/imagecache/imagecache.module on line 208.
warning: filesize() [function.filesize]: stat failed for imagecache/thumb/files/imagename.jpg in [base url]/demo/sites/all/modules/imagecache/imagecache.module on line 209.

Going back to the view after editing (without saving) displays the image as expected?
