This is a bit of a reach, but maybe it would work if you added
commutator links to your operator definitions? You should add 'em
anyway on general principles.
If that *does* fix it, I'd say it's still a bug; index operators
should not have to have commutator links.
Next step would be to burrow in with a debugger and figure out what
function the thing thinks it's trying to call. A backtrace from
the call to elog() would help here.
