Mac OS X 10.5.7, ZFS /Users/timeless (among others) [=home directory]
Steps:
1. run virtualbox
2. select file>Import Appliance
actual results:
VirtualBox.app burns cpu until I realize it's killing my battery.
I don't have a Guest yet, I was trying to import a QNX VMWare file (just for kicks). But it seems clear that this won't work on my system (I don't need the file, I was just curious).

So. I'm aware that this is mostly a bug between Qt and zfs, but this is the only application I have which triggers an infinite loop.

I'm using zfs 119
The code is looping here:
4828 /* static */
4829 QString VBoxGlobal::documentsPath()
4830 {
4831 QString path;
4835 path = QDesktopServices::storageLocation (QDesktopServices::DocumentsLocation);
4839 QDir dir (path);
4840 while (!dir.exists())
4841 dir.cdUp();
http://doc.trolltech.com/4.5/qdir.html#cdUp
bool QDir::cdUp ()
Changes directory by moving one directory up from the QDir's current directory.
Returns true if the new directory exists and is readable; otherwise returns false. Note that the logical cdUp() operation is not performed if the new directory does not exist.
I haven't checked, but cdUp clearly can return an error and the code clearly isn't checking for the error, so I believe the code should be fixed.
