Error creating or resize .gif thumbnails

[Mec4D]

GD Bibliothek

Create thumbnail for: Jogging (2creepyjog_2.gif) ....  
Warning: call_user_func() expects first argument, 'ImageCreateFromgif', to be a valid callback in /xxx/xx/xx/xx/xxx/xxx/xxxx/gallery/includes/image_utils.php on line 65

   Error creating thumbnail

Normal all works ok after I updated with least patch, but if I try to resize the old .gif or .png thumbnails I got error as above.

What is wrong? I don't have any problems with .jpg

Thank you for your support!
