This is a shame. It should be an easy fix. The dialog box is failing in com.apple.QD which is a compatibility framework for older programs that used QuickDraw for their UI. The failure is taking place because when Bryce brings up a dialog, it is saving the area of the screen behind the dialog for when it is dismissed. There’s some problem with the limits used during the restore of the data behind the dialog…it’s overwriting it’s bounds and over-writing sections of memory that are generating segmentation fault exceptions.
Now that is the best, most concise and believable explanation I have read on this problem. Can’t attest to the accuracy, but I’m impressed nonetheless
