Crash by deleting the first measure in parts when key signatures are not in C/or not in concert pitch

Version 2.0.3 3c7a69d / Windows 7

1) Create a score for two flutes with a key signature with at least 1 sharp or 1 flat.
Or load this test file: 2 Flutes in D.mscz

2) Generate parts -> New all -> Ok
3) View part Flute (or Flute1)
4) Press "M" for disable MM rests
5) Select and delete (Ctrl + Del) the first measure

Result: crash

.Notes, and other cases

- No crash with the same score in C: 2 Flutes in C.mscz

- With transposing instruments (eg two sax): 2 sax.mscz

Same result with the same steps. But in another scenario: ie: repeat the same steps, but just before step #5, press "Concert pitch" in the part where you are: so: in C: result: no crash by deleting the first measure

- With a transposing instrument and a non-transposing instrument (eg Bb clarinet and piano): Clarinet Piano.mscz
Same behavior: crash in the clarinet part (except always if you toggle in Concert pitch in this part), no crash in the piano part:
