I'm trying to run an adobe air app, but it chokes when it can't find /usr/lib32/keyringwhatever.so according to strace, so it appears that gnome-keyring neeeds support for multilib.
Nice to see this, I experience this issue when using wine, which throws the following error many times when running basically any application through it:
> p11-kit: couldn't load module: /usr/lib32/pkcs11/gnome-keyring-pkcs11.so: /usr/lib32/pkcs11/gnome-keyring-pkcs11.so: cannot open shared object file: No such file or directory
AFAIK app-crypt/gcr as a dependency would also need x86_abi_32 support to make this work. See https://forums.gentoo.org/viewtopic-p-8020326.html#8020326 for reference about this.
