Resizing GIF animation: BUG/Feature request

Hello,I do not know whether this is a BUG or perhaps should be a feature request. Usually the GIMP does a good job resizing images, but not with this GIF animation: http://pixloads.com/public/pview/45183/halloween31.gif When I scale it down using Image->Scale some ugly black dots get visible. This happens with GIMP 2.4 windows binary. Also on GIMP 2.2.13 under debian. I tried some random shareware utility and it got the job done rigth. Anyone cares to take a look see what is happening with GIMP... ? Carlos. Thanks for bringing wonderful software into existence!

Next time, please send such messages to the gimp-user mailing-list.

Whenever you do anything with a GIF image and don't absolutely need to keep the colortable intact, then convert it to RGB as the first step. I am sure GIMP would have done a decent job at scaling your animation if you had followed this advice and performed the scaling in RGB mode.
