No, checkboxes are correct. You wouldn't want both PD and another license, but dual-licensing in the general case is quite common. For
I know about dual licensing and understand its use in certain cases, I just don't think it is the case in this particular gallery, where the choices are: proprietary, PD and various CC licenses.
example, images uploaded to Wikimedia Commons have to be GNU FDL (or public domain, or fair-use), but if you prefer CC, or if you consider FDL too restrictive and want to license under MIT or BSD, then you can choose dual-licensing, allowing users to pick which license to use.
My understanding is that Wikimedia Commons allows CC or some other licenses whitout a need for dual-licensing http://commons.wikimedia.org/wiki/Commons:Licensing#Acceptable_licenses
A more pertinent example: suppose you're designing the logo for a software project, like Firefox. You want to release under a CC license, but you know that CC licenses do not count as DFSG-free, so to match the rest of the project you can dual-license with CC and GPL (or whatever license the rest of the project uses).
Yup, I release that logo under a dual license and submit it as it to the proper project. But on inkscapegallery.net, where I can upload a PNG version, dual-licensing does not add anything useful.
Licenses are not mutually exclusive: they are additive. When you're working in isolation, dual-licensing is completely unnecessary, but if you're interacting with different groups of people, allowing them to choose a license gives them more freedom to use and reuse your work, which is (I suppose) your aim in using a free license in the first place,
Sure, at openclipart.org, where we encourage people to remix and the uploads are in source format (SVG), a free license make sense. At inkscapegallery.net, where all you do is to show some final results, I am not so sure.
