Hard crash on adding folder

[ghost]

I experienced a hard crash on adding a folder to dupeGuru PE 2.3.0 and I can reproduce it although I haven't identified the underlying cause yet.

1. Launch the app with 2 restored folders: ~/Downloads and iPhoto Library. iPhoto Library is in an Excluded state.
2. Select the ~/Download folder and click the "-" button.
3. Select the iPhoto Library item and click the "<" button which replaced the "-" button (to un-exclude).
4. Click on the "-" button.
5. Click on the "+" button.
6. In the file dialog, select the ~/Downloads folder and click open.
7. Crash

The log is attached.

It really has something to do with two root folders with the second being the iPhoto Library in excluded state. I tried a couple of other possibilities (another folder in excluded state, the iPhoto Library in normal state, etc) and I didn't get the crash. On point 6 however, it's not important that it's the ~/Downloads folder that is being added. I tried another folder and it crashed too.

Oh, here's something interesting: This crash doesn't happen in 32-bit mode.

It looks like I'll have to update to the latest version of pyobjc (I see in the changelogs that libffi was updated to fix x86_64 issues). I hope that it will not cause too much troubles.

I updated pyobjc on my dev machine to the repo's tip (eebec14eca41) and it fixed the problem. There have been many changes in pyobjc in between this version and the one that I was using before (namely a big and cool-looking change in the way metadata is handled) so I hope it will not cause new problems, but I'll try it for a while before I update pyobjc on my build machine (and I'll set the ticket as fixed after I've updated the build machine).

I've updated the OS X build machine to pyobjc's current tip.
