VM VirtualBox Manager GUI crash when deleting snapshot

[Alil]

Host: Win7 x64
Guest: SLES 10 SP3 x64 w/o GA

Manager GUI crashes when trying to delete (merge) snapshot for running machine.
It is reproducible on new machine.
If snapshot has saved state it loses it before crash. That VM and other ones are not affected and are running.

Seems to be caused by #7966. Ticket can be closed.

I've got the same problem on host win 7 64 pro.

Not so easy to reproduce because it requires a 7 hour restore. I've not got a log for it yet. It happened on a one VD guest of Win10 64, and also a 4 VD guest of Ubuntu 16.04.

I'm also suffering from this issue (Windows 7 Professional x64 host). One minute the merge was running, suddenly the window was just gone. No error message was displayed. The differencing images were gone but not actually merged. The snapshot remained in the list, but since the files were gone, the VM was unusable and I had to restore from backup. I just lost 6 hours of work due to this!!! Please fix this as soon as possible.

So far I see 3 report from Windows users. We need areproduction scenrio to fix this. Or at least a Windows crash dump.
