No, unfortunately I couldn't find any reason. I repeated it a few times 
with the same results but I no longer have access to the VM I tested 
this on so I can't help with more details, sorry :/

If it does not happen when you try it (if you do), I would be glad to 
hear about so I can call this a fluke and attribute the bug to special 
unknown circumstances with the particular host system I used.
