[Shotwell] Delete picture with shotwell

[Roumano]

Hi,

I was facing a bug but i don't known if it's a already known :

1) I'm importing picture form my camera ( Raw + Jpg ) via shotwell
2) Move to trash one of them (or several) via shotwell
3) See the trash on shotwell, then select them & delete them

--> The .cr2 (raw format) is not delete
I'm using Shotwell 0.11.5

Regards

PS : Another question: why a picture named "_cr2_embedded.jpg" are
always created when a raw file exist ? (needed by shotwell ? )
