Code review comment for lp:~elopio/ubuntu-ui-toolkit/fix1314390-click_element_on_unity

Do you mean this error condition?

25 + if top_container is None:
26 + raise _common.ToolkitException(
27 + "Couldn't find the top-most container.")

It will just happen if no parent has a global rect. Which is an unlikely case, but could happen.
