SEGFAULT trying to edit planned dive

[Sergey Starosek]

Hi,

Got SEGFAULT today while testing. Step to reproduce:

1. Start with clean data file (close previous one)
2. Plan new simple dive (10m - 10min, 5 m - 5 min, 0m)
3. Press OK
4. Right click and choose Edit dive
5. SEGFAULT

backtrace attached.
