Crashes while collecting files to scan

[pcolsen]

Instructions

DupGuru fails when beginning to collect files to be scanned. I've tried this with several different directories, restarting the program several times. This is a recent failure. I've been using the program heavily, sometimes scanning as many as 34000+ files. This was a sudden and complete failure. I can't get it to collect files in any directory. The only change I made was to move several files out of a directory before I attempted to scan it. I had scanned the directory before, but I moved some subdirectories out before trying to scan it again. I don't believe that I changed anything else that would affect the program's operation. I cleared the picture cache and tried again but still without success. The error occurs only in photo mode and only in the "content" mode. The EXIF Timestamp mode works correctly. The Standard and Music modes work correctly on the same directory.

I get the same error. It had been working for a while but after I cleared out a bunch of duplicates and changed the filters this showed up.

I just built new initial binaries for OSX for 4.0.4 which most likely fixes this issue, over at: #566 (comment). If you would like to give one of those a try and let me know if that works that would be helpful. This is most likely related to #439.
