Data and media are not programs. They can be distributed with
GPL-licensed sofware without breaking the GPL. They therefore do not
require compatibility with the GPL.
It is very easy to imagine scenarios in which BY-SA would clash with
GPL licensed programs (any in which BY-SA media becomes a software
resource encoded in a programming language or is expressed
programatically, e.g. a PostScript image). But it is not necessary to
structure a program in this way.
Where BY-SA and the GPL do seem to clash are web pages using
HTML/CSS/images which should be under BY-SA and JavaScript which should
be under the GPL. Likewise for Flash projects. If the GPL or BY-SA
prevent a license comment such as "Text and images BY-SA, code GPL" they
should be modified to allow it. If they do not, a standard example of
such licensing should be provided. :-)
