Crash when adjusting datetime of multiple event with only one selected

[jeremypw]

What Happened?

• Added "New Event" to a group of two "No Event" photos (screenshots)
• This created a single undated event containing two photos
• Selected only one of the photos and chose "Adjust Date and Time".
• Chose a date (yesterday) from the dialog, otherwise defaults
• On pressing "Apply" Photos crashed.

Steps to Reproduce

See above description

Expected Behavior

It should not crash. Not sure what the correct result is when creating a merged event containing one dated and one undated event. Probably apply date time to all the components of the event.

OS Version

6.x (Odin)

Software Version

Are you still seeing this? On 6.1 I can't seem to repro this.
