Bug#547699: gmameui: read_pixbuf_from_zip_file implicitly converted to pointer

[Loïc Martin]

Hi,
I'm really sorry - I didn't get email notifications for this bug, and
thus ignored you guys. Thanks to Paul Wise for sending me an email.

The bug is reportedly fixed upstream, see
http://gmameui.cvs.sourceforge.net/viewvc/gmameui/gmameui/src/gmameui-zip-utils.h?r1=1.1&r2=1.2&view=patch

It's in 0.2.12, but since I've got issues with 0.2.12, I'll try to
release a patched 0.2.11-3 with upstream's patch.

Thanks a lot Dann Frazier and Martijn van Brummelen.
