[FIXED in 1.3] Bug Report - removing a tie between notes across measure results in a EXC_BAD_ACCESS (SIGBUS) (MAC OS)

- OS: Mac OSx Build 11G63
- Musescore 1.2

Workflow resulting in Exception..
- Editing a new score (attached), I attempted to remove a tie between notes that spanned a bar line. I clicked on the first note and clicked the 'tie' indicator in the palette.
- Clicked delete, tie was still in place
- Saved the score, closed the score, closed Musescore.
- Opened Musescore and attempted to reopen the score via Open->Recent
- SIGBUS exception thrown. I am no longer able to open the score.

More on info from stack trace displayed when trying to open the score:
