Unable to set master disk

[Clayton Dukes]

I get the following error when trying to select my master disk:

Assertion failed: [hd->children().size() == 0 && hd->machineId() == mData->mUuid] at '/home/vbox/vbox-1.3/src/VBox/Main/MachineImpl.cpp' (1614) in virtual nsresult Machine::DetachHardDisk(PRUint32, PRInt32). Please contact the product vendor!.

Result Code: 0x80004005 Component: Machine Interface: IMachine {fd443ec1-0009-4f5b-9282-d72760a66916}
