From email:

I tried to run it on a OSX 9 Mavericks (Developer preview 8) and got into trouble once. I enclose the feedback from Console, maybe with this you can anticipate on coming problems once Mavericks will be released. see 2 attachments. I encountered the problem on OSX 10.9, but I don't know it it is Mavericks-related.

During comparing the content of two disk-partitions (one on an internal disk and one on an external disk on firewire-800), after working and trimming quite some time in the compare i suddenly got this errorpanel below (stackdump retrieved from Console), suggesting to quit the application. I first tried to save the search results (see enclosed file, but they were indeed not reliable : contain a lot of unknow filenames : ’—‘) I think to remember the issue happened right after a key-combination (command-ctrl-A or command-t (i'm not shure which one))

Got it! I could reproduce the problem:

1. Run a scan
2. Sort results by Dupe Count
3. Enable delta values
4. Enable Dupes Only.

Crash.

BTW: it had nothing to do with OS X.
