I was building a new sequence from scratch.
I began with a template sequence, saved it under a new name.
I changed the media file to point to the correct media file.
I imported two timing files that were successful.
During the import of the third timing file Nutcracker halted with the attached crash file.
One thing I noted that Nutcracker went into the 'Not Responding' mode for a long period before producing the crash report.
I have included the timing file that NC was crashing attempting to import.
This is a repeatable crash.
