Crash when deleting dives

[Henrik Brautaset Aronsen]

I tried deleting the 4 topmost dives, and Subsurface crashed:

Thing is, I've only managed to reproduce it twice.  As far as I can 
remember, I just looked at a couple of dives, maybe opened one of the 
dives in an editor, but didn't actually edit anything.  Frustrating.

Dirk, Linus: You can use the henrik.xml file you received to try to 
reproduce it.
