Public bug reported:
The 32-bit GTK+ compatibility libraries shipped with Ubuntu 7.10 appear to be
missing the svg decoder. This means that decoding some of the stock icons
shipped with the system fail when running a 32-bit Gnome binary on an amd64
system.
I have attached a minimal test case to demonstrate this issue. Build the
program like this:
gcc -o testgtkicons testgtkicons.c `pkg-config gtk+-2.0 --cflags
--libs`
If you build and run it on a 64-bit system, it should show a window
containing the default icon used with "cancel" buttons in Gnome.
Likewise on a 32-bit system. But if you build it on a 32-bit system and
then try to run it on a 64-bit system, you'll get this error message to
stderr:
(testgtkicons:24211): Gtk-WARNING **: Error loading theme icon 'gtk-
cancel' for stock: Unable to load image-loading module:
/usr/lib32/gtk-2.0/2.10.0/loaders/svg_loader.so:
/usr/lib32/gtk-2.0/2.10.0/loaders/svg_loader.so: cannot open shared
object file: No such file or directory
...and more importantly: the icon will show up as a "broken document"
image since GTK+ couldn't load it.
If you were to copy the following libraries and symlinks from a 32-bit
Ubuntu 7.10 install into the proper lib32 directories on the 64-bit
system, the problem goes away:
/usr/lib/libcroco-0.6.so.3
/usr/lib/libcroco-0.6.so.3.0.1
/usr/lib/libgsf-1.so.114
/usr/lib/libgsf-1.so.114.0.7
/usr/lib/librsvg-2.so.2
/usr/lib/librsvg-2.so.2.18.2
/usr/lib/gtk-2.0/2.10.0/loaders/svg_loader.so
...so it seems like these files probably just need to be added to the
ia32-libs-gtk package, if the solution is really that simple.
