-----------------------------------------------------------------------
I can add a bit of insight into the problem, having experienced it myself and
looked into why.
It seems that VirtualBox's RDP server doesn't announce capabilities in the
correct order. There is a flag or setting that could be configured when calling
FreeRDP2's API that will make this non-fatal.
