If i crop a watermark image with GIFBUILDER, it will work with a crop-X-value of 0.
If i crop with a X-value of 30 it will throw a error (see screenshot)

There is a incomplete filename in the call imageCreateFromFile("/home/www/p384125/html/typo3/fileadmin/_processed_/5/d/csm_3D_a059d90")
This immage ist correctly saved in .._processed_/5/d/ with filename csm_3D_a059d90350.gif

my code for the watermark:

    file = GIFBUILDER
    file {
        XY = [10.w],[10.h]
        format = jpg
        quality = 90
        maxW = 1920
        maxH = 1080

        10 = IMAGE
        10 {
            file {
                import.field = uid
                treatIdAsReference = 1
                width.field = imageWidth
                maxW.field = maxImageWidth
                maxW.noTrimWrap = ||c|
                #crop = 0,0,1498,829
                crop = 30,0,1498,829
            }
        }

        15 = IMAGE
        15.file = fileadmin/copyright.png
        15.mask = fileadmin/copyright-mask2.png
    }
