Description of problem:
Installing from a live usb onto an empty partition that used to contain F19. After I select the volume to install to and click 'Done', this error occurs. Both automatic and 'let me choose' partitioning modes result in a similar crash. 

Version-Release number of selected component:
anaconda-core-21.48.21-1.fc21.x86_64
