What do I do to fix this? Replying to dkocher:

Can you please try if still see this issue with the current snapshot build by updating from within Cyberduck in Preferences → Update → Automatically check for updates in → Snapshot Builds.

I have applied the update. The program continues to crash. I will attach the report later today.
