[vbox-dev] IProgress_waitForCompletion gives error randomly.

I did more test, I get this error on all IProgress_waitForCompletion,
IProgress_getPercent and IProgress_getCompleted. So far, I only get the
error when I call IConsole_powerDown on a running VM, when it happens, I get
this text in the vboxwebsrv console.

API return code:  0x800706BA (Unknown Status 0x800706BA)
COM error info result code: 0x0
COM error info text:

It is a COM error, it should be the vbox control, not my code, any idea how
to solve it?

I don't believe these are "random" errors - 0x800706BF means "The remote 
procedure call failed and did not execute".

Since I'm not using the webservice on Windows I can't provide hints what 
could lead to this error.
