Crunching problems when uploading 1 pixel high image

When I try to upload an image that is 880x1px the cruncher fails with the following:

Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /home/wisdm/hi/wp-includes/media.php on line 1010

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/wisdm/hi/wp-includes/media.php on line 428

Warning: imagepng(): supplied argument is not a valid Image resource in /home/wisdm/hi/wp-includes/media.php on line 454
70

I’ve tried both GIF and PNG, neither have transparency enabled it that becomes an issue.

I’ll work around the problem with ftp but thought someone should know.
