PyWeek - What's up with my GL?

I believe something is terribly wrong. I decided to load some gifs into the game and suddenly this appears:

(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_copy: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_width: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_height: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_n_channels: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_rowstride: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_has_alpha: assertion `GDK_IS_PIXBUF (pixbuf)' failed
(process:8779): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_pixels: assertion `GDK_IS_PIXBUF (pixbuf)' failed

After some debugging I believe they originates from the line:
image = pyglet.resource.animation("solider_forwards.gif")
The error does not appear for my teammate j-1, so I'm suspecting my installation of OpenGL. Does anyone have an idea of what to do about it?

EDIT: Found this. It appears more people than me are experiencing these problems. Perhaps it's time to scrap the gif plan...

... why is it using Gdk? its got nothing todo with Opengl (its a Gnome library)... this is what you get when you hack together a bunch of libraries (such as gdk) that arn't ment to be used this way instead of just using sdl... its not an opengl issue, its just pyglet
we are using SDL/Gl and just using numbered .png's for animation (foo_0.png, foo_1.png and so on)

gdk is used by pyglet to load images

Correction: I do get the error on my laptop, using Ubuntu, but not from within Gentoo on my stationary.

I found the source of the bug, and a naive workaround, but no real fix, and filed a bug report to pyglet. I guess we will have to use the multiple png method, for the time being.
