Hello,
I have code where i manually reorder an outline view, and when it is
reordered it automatically resizes to fit all the items. A crash
consistently happens when I move a subitem from one group to another
(in other words, when I drag a row so that it is originally in one
expandable row and is put in another). I have spent a day trying to
track this down with no luck, and it works fine when I rearrange rows
in their own subgroup (as in they stay under the same expandable row).
Exception Type: EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000020
