[vbox-dev] Occasional Hang when saving machine state - data loss

the issue https://www.virtualbox.org/ticket/7756 is still present in 4.3 version 
and causes virtual disk data loss. It happens on Windows and Linux hosts. There 
is report https://www.virtualbox.org/ticket/7756#comment:64 of Access Violation 
exception somewhere in Qt4 library.

Could you please help to resolve it ? My guess is that the default verbosity of 
VirtualBox logs is not sufficient to diagnose it. I read about logging options 
https://www.virtualbox.org/wiki/VBoxLogging but I'm still not sure what option 
to use.

Thanks, Petr
