Pro Tools Unexpectedly Quits when I try to perform a "Consolidate Selection." This started happening just after upgrading to Pro Tools 5.3.1.

In one case, a corrupt session was to blame. To fix:
-Create a new session and use the File>Import Tracks command to transfer the tracks into the new session file.
