When you create a gallery in 3.3.1 (assuming any version tbh), the link to the attachment doesn't work, because wpthumb is trying to use the function imagesize on a permalink/single picture template, i.e. /attachment/1/ . I've seen other image handling solutions first check if the file/path is actually an image and only then run the function.

line 1480 of GdThumb.inc (so not even wpthumb).
