19071	W10 Guest crash when watching youtube videos	Pablo Sanchez		"Hi,

When I found 6.0.14 crashing, I tested with the latest nightly[1] and Extension[1.5].

My Host O/S is openSUSE Tumbleweed.  I am up to date[2].

The Guest O/S is an up to date W10 VM.

While watching a youtube video (any will do), the VM crashes.

The following errors are logged.  First, in /var/log/messages:

{{{

}}}

after, in VBoxSVC.log:

Nothing is placed in VBox.log

Please let me know what other data is needed.  I am sure you need more.  ;)
