VirtualBox 4.0 final Manager occasional crash, Qt related?

I think this is a regression from 3.x and even from 4.0 beta3. I've never experienced it before that. I only know that it happens when closing the Manager. It happened to me at least 2 times, using identical steps: creating an XP 32 bit VM, modifying some settings in the VM settings window, without starting the VM, followed by an idle time, leaving the Manager opened and working on something else on the PC (for several minutes, unrelated to VB), then trying to close the Manager, followed by instant crash. At least two of the crash backtraces that I've managed to observe (including the current dump), pointed to Qt. I've seen one other backtrace that pointed to ntdll or kernel32.dll (I don't remember which one). I can't reproduce it at will, I don't understand it yet.
My system: Windows XP SP3 32 bit
