Qt Camera in QML Dies after closes the drawer with Camera

Hi , 

   would like to report the bugs i experiencing in Linux desktop , 

using Camera  . 

the scenario , i put the Camera inside Drawer  (acts like modal) 

using "capture button" it will open the Drawer with Camera 

at first open the camera works with no problem but after the drawer closes and re-click the button , the drawer opens but the camera doesn't work anymore , deploying the source code to my android the feature is working with no problem , 

i added this 2 signal 

 onAboutToHide:

onAboutToShow:

to make sure that the camera only work when the drawer triggered
