After investigating some more I was able to create a working minimal case:
https://mega.nz/#F!v85XnbYQ!6otxvpXyfNU7jUTVbx5ohA

Theres a Video, the Save and the log.
It reliably crashes the game, if its the first save I load after loading the game.

//Edit: Minimal-er Case
As you can see in this Video apparently the problem is the playback at an impossible position of the sound file.

I think I can't narrow it down even more, at least not without some more debugging-tools

Let me know if you have more ideas

You, sir, deserve a cookie. The video was the clue we needed to understand what is going on. Due to an error in the inserter activity function, that returned negative number in this case, the position in the sound sample was also set to a negative value.
This was most probably the cause of all these problems.

I fixed the cause, and I also added strict check of the value in our sound internals, so the game crashes for everyone if similar things happen, so we would find out sooner.

Fixed for 0.12.7

I'm glad I was able to help
Don't forget to tell the allegro guys, so they can also include a check for negative sample positions.

I will go and eat a cookie now
