Here's a reproducible test case that yields a similar crash report:

  File | New | Census
  Census | Edit cell
    arbitrarily change the two radiobox selections at the top
  press right-arrow thrice, moving focus to the rightmost column
  Census | Edit cell
    revert both radiobox changes made above
  F2 [causes a segfault, repeatably]

It crashes in wxDataViewCtrl::DoSetCurrentItem(wxDataViewItem const&)
when the number of columns changes.
