Hello,

After the Virtualbox update from the version 5 to version 6 series:

Invoking copy/paste operations when shared clipboard is turned on causes the guest machine to immediately abort
Even with shared clipboard turned off in Virtualbox settings, guest machines generate an Abort status in Virtualbox during a normal shutdown
/var/log/messages indicates a segmentation fault in Virtualbox shclipboard application
These aborts do not occur when running Virtualbox over a ssh-X tunnel

I'm wondering if this is related to the older nx-libs problem with shared clipboard submitted by mikedep333.

x2go client: v 4.1.2.2 (Qt 5.15.2) running on Fedora 33

x2go server: : 4.1.0.3, nxproxy 3.5.99.26
