[O] Org-mode 7.7 Broken with respect to mouse and checklists?

[Patrick Brennan]

Hi,

I have a checklist in this form:

    - [ ] Item One

    - [ ] Item Two

In Org-mode 7.7, if I put my mouse inside one of the checks and press the left button, I get the following message:

org-open-at-point: Wrong type argument: markerp, 471

The number changes depending upon where the checkmark is.

This works fine in org-mode 7.4 and 7.6. Any clues what I'm doing wrong in 7.7?

Thanks,

Patrick
