VM not paused when creating a snapshot from GUI

[markba]

When trying to make a snapshot from GUI of a running session, after the dialog for entering the snaphot name is passed, the following error pops up:

A session for the machine 'Ubuntu JeOS' is currently open (or being closed).

Result Code: 
E_ACCESSDENIED (0x80070005)
Component: 
Machine
Interface: 
IMachine {1e509de4-d96c-4f44-8b94-860194f710ac}
Callee: 
IVirtualBox {557a07bc-e6ae-4520-a361-4a8493199137}

When doing the same in the session menu or via CLI, all succeeds well, so it's clear it's possible to do a snapshot of a running session.

This can be of interest: when the name dialog is popped up (while creating the snapshot from the session menu), the session is *paused*. This (the pausing) is not happening when creating a snapshot from the generic menu, probably resulting in the error above.

So the possible solution could be that the GUI must pause the session while doing the snapshot.

Please could you attach a VBox.log file for a VM session where you tried to take a snapshot from the GUI?
