Crash when using a shortcut for removing selected tra

Cubase Pro 8 on a PC Windows 7 64bits, CPU Intel i7, 32g of RAM

This one is pretty weird…
When I use the shortcut that I have set for “Remove Selected Tracks”, Cubase crash sometimes (I happened on a big template of 300 tracks)…but when I use righ click - Remove Selected Tracks, no problem.

The shortcut I assigned in the Key Command editor, is : Shift+Del
Another note :

Am I the only one experiencing that?
