GPLv2 icon with GPLv3+ program

[Ulrik Sverdrup]

I know this is a gray area, but I want to know if this list, or gnome
artist, have opinions about GPLv2 icons to GPLv3 programs
compatibility.

The default gnome icon theme is released under GPLv2 (only). With my
GPLv3+ program I want to distribute an icon derived from gnome's
default icon theme: I'm taking insert-object.svg and making object.svg
(a blue box, attached).

I combine the GPLv2 icon with my python program at runtime like so:

pixbuf = gtk.gdk.pixbuf_new_from_file_at_size(icon_path, size,size)
gtk.icon_theme_add_builtin_icon(icon_name, size, pixbuf)

Now, is it compatible? Is the icon now "linked" to my program, so I
can not use it?

Thank you for any input, or any links to where this specific question
is discussed,
Ulrik

Slightly tangential, but FWIW we switched gnome-themes to LGPL a few  
years ago, because it seemed that an icon theme more closely resembled  
a library than an application.  But whole question of if/when/how  
icons were 'linked' to an application was pretty unclear when we made  
that choice, too.

Cheeri,
Calum.

Ok. But still only to an older (potentially) GPLv3-incompatible
version? I acquired gnome-icon-theme from debian whose copyright file
only mentions GPLv2.

Ok. You say *Lesser* GPL. Just FYI: I have gnome-themes and
gnome-icon-theme version 2.26 installed, and in the debian copyright
for these two packages, it still says GPLv2 (only) (Not LPGL, but
GPL).

Hmm... gnome-themes changed to LGPL on 2003-08-11, according to its  
ChangeLog:
<http://git.gnome.org/cgit/gnome-themes/tree/ChangeLog.pre-git>

And here's its current COPYING file:
<http://git.gnome.org/cgit/gnome-themes/tree/COPYING>

Cheeri,
Calum.

Ok Will file bug in debian.

However what I checked before asking here was not gnome-themes, but
gnome-icon-theme. I hope that is still on topic on this mailing list.
I checked the release tarball (and did again just now) and 2.26.0 of
gnome-icon-theme [
http://ftp.gnome.org/pub/GNOME/sources/gnome-icon-theme/2.26/ ] ships
with a GPLv2 license COPYING file.
