nightly 755bf05 Ubuntu 16.10

1. New Score with at least four different instruments
2. Parts... -> "New All" -> "Ok"
3. Parts... -> "Delete" all parts -> "New All" -> "Ok"

Result: Crash

If you don't have different instruments, it won't crash but create too much parts.

Stack trace:
1 Ms::mscoreMessageHandler musescore.cpp 2348 0x48b856
2 Z14qFloatDistancedd 0x6888d42a
3 ?? 0x21f279d0

7 OVE::binaryToHarmonyType ove.cpp 5744 0x530041

So it dies on an assert()

Yes it doesn't fail at the same point in the program. The problem here is the swap operation directly because the lastPos has a value wich isn't available in the list. The problem in the other case is that after a swap the title is not avialabile on the refferred adress anymore and this causes the error.
So I would say same reason but different output.
But it would be kind if you could test this again with windows.
