General Support: Error message on *some* images when importing

Happens to about 1 in 100 images, always happens with the same image, error code is displayed in the thumbnail preview in the import section also, if the errored pic is ticked for import it screws that whole album, only way to fix is to telnet in (image gets locked in ftp) and delete the image then and only then is it possible to nav into manage albums and delete the image in question. If the image is still there the whole admin interface hangs.

My question is, is it a bug in the gallery or a problem with the pictures themselves or a combination of both? ie slight problem with images that the gallery dosent know how to deal with ie ala screw up?

Code is below..
