i'm using f8187c9 on kxstudio 12.04.

To reproduce :
1- Create new score with unpitched percussion like snare drum
2- Press the N key
3- try to click on note shape at the bottom of the window to enter note in the score
4- mscore crashes

here is the gdb backtrace :

I can reproduce every time I try.

Here is the result from bt command in gdb :
