No test cases?

I believe we have a per_inventory test suite, so you could test it at
that level.

Otherwise:

 review needs_fixing
 merge approve

review: Needs Fixing

[Vincent Ladeuil (vila)]

I was about to ask for tests then I saw https://bugs.edge.launchpad.net/bzr/+bug/403523/comments/1

From there I conclude you got that patch covered by some failing test[s].

It's true this is covered by a blackbox test in 2a, but I'll look at doing a per-inventory one. If it's hard I'll probably skip it though.

test_inv has a comprehensive set of parameterised tests I added for apply_delta; should be trivial to add another case there - gimme a shout if its not obvious.
