Default [Q] [Problem] Xperia SP MIUI - Camera crashes

I installed this ROM few days ago

[ROM][SP][JB][4.2.2][UNOFFICIAL]MIUI XPERIA SP V9 [4.3.7][3MAR] {RELEASED}
http://forum.xda-developers.com/show....php?t=2505052

all is running smoothly except the camera. It crashes randomly when i use the vol button to do zoom in / out. Also crashes every time switch the camera/video control.
Any idea to fix it or is a ROM issue?
Thank you
